  This operation performs non_max_suppression on the inputs per batch, across

  all classes.

  Prunes away boxes that have high intersection-over-union (IOU) overlap

  with previously selected boxes.  Bounding boxes are supplied as

  [y1, x1, y2, x2], where (y1, x1) and (y2, x2) are the coordinates of any

  diagonal pair of box corners and the coordinates can be provided as normalized

  (i.e., lying in the interval [0, 1]) or absolute.  Note that this algorithm

  is agnostic to where the origin is in the coordinate system. Also note that

  this algorithm is invariant to orthogonal transformations and translations

  of the coordinate system; thus translating or reflections of the coordinate

  system result in the same boxes being selected by the algorithm.

  The output of this operation is the final boxes, scores and classes tensor

  returned after performing non_max_suppression.

  Args:
    boxes: A `Tensor` of type `float32`.
      A 4-D float tensor of shape `[batch_size, num_boxes, q, 4]`. If `q` is 1 then

      same boxes are used for all classes otherwise, if `q` is equal to number of

      classes, class-specific boxes are used.
    scores: A `Tensor` of type `float32`.
      A 3-D float tensor of shape `[batch_size, num_boxes, num_classes]`

      representing a single score corresponding to each box (each row of boxes).
    max_output_size_per_class: A `Tensor` of type `int32`.
      A scalar integer tensor representing the maximum number of

      boxes to be selected by non max suppression per class
    max_total_size: A `Tensor` of type `int32`.
      An int32 scalar representing the maximum number of boxes retained over all

      classes. Note that setting this value to a large number may result in OOM error

      depending on the system workload.
    iou_threshold: A `Tensor` of type `float32`.
      A 0-D float tensor representing the threshold for deciding whether

      boxes overlap too much with respect to IOU.
    score_threshold: A `Tensor` of type `float32`.
      A 0-D float tensor representing the threshold for deciding when to remove

      boxes based on score.
    pad_per_class: An optional `bool`. Defaults to `False`.
      If false, the output nmsed boxes, scores and classes

      are padded/clipped to `max_total_size`. If true, the

      output nmsed boxes, scores and classes are padded to be of length

      `max_size_per_class`*`num_classes`, unless it exceeds `max_total_size` in

      which case it is clipped to `max_total_size`. Defaults to false.
    clip_boxes: An optional `bool`. Defaults to `True`.
      If true, assume the box coordinates are between [0, 1] and clip the output boxes

      if they fall beyond [0, 1]. If false, do not do clipping and output the box

      coordinates as it is.
    name: A name for the operation (optional).

def crop_and_resize(image, boxes, box_ind, crop_size, method="bilinear", extrapolation_value=0, name=None):
  r"""Extracts crops from the input image tensor and resizes them.

  Extracts crops from the input image tensor and resizes them using bilinear

  sampling or nearest neighbor sampling (possibly with aspect ratio change) to a

  common output size specified by `crop_size`. This is more general than the

  `crop_to_bounding_box` op which extracts a fixed size slice from the input image

  and does not allow resizing or aspect ratio change.

  

  Returns a tensor with `crops` from the input `image` at positions defined at the

  bounding box locations in `boxes`. The cropped boxes are all resized (with

  bilinear or nearest neighbor interpolation) to a fixed

  `size = [crop_height, crop_width]`. The result is a 4-D tensor

  `[num_boxes, crop_height, crop_width, depth]`. The resizing is corner aligned.

  In particular, if `boxes = [[0, 0, 1, 1]]`, the method will give identical

  results to using `tf.image.resize_bilinear()` or

  `tf.image.resize_nearest_neighbor()`(depends on the `method` argument) with

  `align_corners=True`.

  Args:
    image: A `Tensor`. Must be one of the following types: `uint8`, `uint16`, `int8`, `int16`, `int32`, `int64`, `half`, `float32`, `float64`.
      A 4-D tensor of shape `[batch, image_height, image_width, depth]`.

      Both `image_height` and `image_width` need to be positive.
    boxes: A `Tensor` of type `float32`.
      A 2-D tensor of shape `[num_boxes, 4]`. The `i`-th row of the tensor

      specifies the coordinates of a box in the `box_ind[i]` image and is specified

      in normalized coordinates `[y1, x1, y2, x2]`. A normalized coordinate value of

      `y` is mapped to the image coordinate at `y * (image_height - 1)`, so as the

      `[0, 1]` interval of normalized image height is mapped to

      `[0, image_height - 1]` in image height coordinates. We do allow `y1` > `y2`, in

      which case the sampled crop is an up-down flipped version of the original

      image. The width dimension is treated similarly. Normalized coordinates

      outside the `[0, 1]` range are allowed, in which case we use

      `extrapolation_value` to extrapolate the input image values.
    box_ind: A `Tensor` of type `int32`.
      A 1-D tensor of shape `[num_boxes]` with int32 values in `[0, batch)`.

      The value of `box_ind[i]` specifies the image that the `i`-th box refers to.
    crop_size: A `Tensor` of type `int32`.
      A 1-D tensor of 2 elements, `size = [crop_height, crop_width]`. All

      cropped image patches are resized to this size. The aspect ratio of the image

      content is not preserved. Both `crop_height` and `crop_width` need to be

      positive.
    method: An optional `string` from: `"bilinear", "nearest"`. Defaults to `"bilinear"`.
      A string specifying the sampling method for resizing. It can be either

      `"bilinear"` or `"nearest"` and default to `"bilinear"`. Currently two sampling

      methods are supported: Bilinear and Nearest Neighbor.
    extrapolation_value: An optional `float`. Defaults to `0`.
      Value used for extrapolation, when applicable.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `float32`.

  r"""Decode and Crop a JPEG-encoded image to a uint8 tensor.

  The attr `channels` indicates the desired number of color channels for the

  Accepted values are:

  

  *   0: Use the number of channels in the JPEG-encoded image.

  *   1: output a grayscale image.

  *   3: output an RGB image.

  

  If needed, the JPEG-encoded image is transformed to match the requested number

  of color channels.

  

  The attr `ratio` allows downscaling the image by an integer factor during

  decoding.  Allowed values are: 1, 2, 4, and 8.  This is much faster than

  downscaling the image later.

  

  

  It is equivalent to a combination of decode and crop, but much faster by only

  decoding partial jpeg image.

  Args:
    contents: A `Tensor` of type `string`. 0-D.  The JPEG-encoded image.
    crop_window: A `Tensor` of type `int32`.
      1-D.  The crop window: [crop_y, crop_x, crop_height, crop_width].
    channels: An optional `int`. Defaults to `0`.
      Number of color channels for the decoded image.
    ratio: An optional `int`. Defaults to `1`. Downscaling ratio.
    fancy_upscaling: An optional `bool`. Defaults to `True`.
      If true use a slower but nicer upscaling of the

      chroma planes (yuv420/422 only).
    try_recover_truncated: An optional `bool`. Defaults to `False`.
      If true try to recover an image from truncated input.
    acceptable_fraction: An optional `float`. Defaults to `1`.
      The minimum required fraction of lines before a truncated

      input is accepted.
    dct_method: An optional `string`. Defaults to `""`.
      string specifying a hint about the algorithm used for

      decompression.  Defaults to "" which maps to a system-specific

      default.  Currently valid values are ["INTEGER_FAST",

      "INTEGER_ACCURATE"].  The hint may be ignored (e.g., the internal

      jpeg library changes to a version that does not have that specific

  r"""Function for decode_bmp, decode_gif, decode_jpeg, and decode_png.

  Detects whether an image is a BMP, GIF, JPEG, or PNG, and performs the

  appropriate operation to convert the input bytes string into a Tensor of type

  dtype.

  

  *NOTE*: decode_gif returns a 4-D array [num_frames, height, width, 3], as

  opposed to decode_bmp, decode_jpeg and decode_png, which return 3-D arrays

  [height, width, num_channels]. Make sure to take this into account when

  constructing your graph if you are intermixing GIF files with BMP, JPEG, and/or

  PNG files. Alternately, set the expand_animations argument of this function to

  False, in which case the op will return 3-dimensional tensors and will truncate

  animated GIF files to the first frame.

  

  *NOTE*: If the first frame of an animated GIF does not occupy the entire

  canvas (maximum frame width x maximum frame height), then it fills the

  unoccupied areas (in the first frame) with zeros (black). For frames after the

  first frame that does not occupy the entire canvas, it uses the previous

  frame to fill the unoccupied areas.

  Args:
    contents: A `Tensor` of type `string`. 0-D. The encoded image bytes.
    channels: An optional `int`. Defaults to `0`.
      Number of color channels for the decoded image.
    dtype: An optional `tf.DType` from: `tf.uint8, tf.uint16, tf.float32`. Defaults to `tf.uint8`.
      The desired DType of the returned Tensor.
    expand_animations: An optional `bool`. Defaults to `True`.
      Controls the output shape of the returned op. If True, the returned op will

      produce a 3-D tensor for PNG, JPEG, and BMP files; and a 4-D tensor for all

      GIFs, whether animated or not. If, False, the returned op will produce a 3-D

      tensor for all file types and will truncate animated GIFs to the first frame.

  The attr `channels` indicates the desired number of color channels for the

  Accepted values are:

  

  *   0: Use the number of channels in the JPEG-encoded image.

  *   1: output a grayscale image.

  *   3: output an RGB image.

  

  If needed, the JPEG-encoded image is transformed to match the requested number

  of color channels.

  

  The attr `ratio` allows downscaling the image by an integer factor during

  decoding.  Allowed values are: 1, 2, 4, and 8.  This is much faster than

  downscaling the image later.

  

  

  This op also supports decoding PNGs and non-animated GIFs since the interface is

  Args:

      If true try to recover an image from truncated input.
    acceptable_fraction: An optional `float`. Defaults to `1`.
      The minimum required fraction of lines before a truncated

      input is accepted.
    dct_method: An optional `string`. Defaults to `""`.

      default.  Currently valid values are ["INTEGER_FAST",

  r"""JPEG-encode an image.

  `image` is a 3-D uint8 Tensor of shape `[height, width, channels]`.

  

  The attr `format` can be used to override the color format of the encoded

  output.  Values can be:

  

  *   `''`: Use a default format based on the number of channels in the image.

  *   `grayscale`: Output a grayscale JPEG image.  The `channels` dimension

      of `image` must be 1.

  *   `rgb`: Output an RGB JPEG image. The `channels` dimension

      of `image` must be 3.

  

  If `format` is not specified or is the empty string, a default format is picked

  in function of the number of channels in `image`:

  

  *   1: Output a grayscale image.

  *   3: Output an RGB image.

  Args:
    image: A `Tensor` of type `uint8`.
      3-D with shape `[height, width, channels]`.
    format: An optional `string` from: `"", "grayscale", "rgb"`. Defaults to `""`.
      Per pixel image format.
    quality: An optional `int`. Defaults to `95`.
      Quality of the compression from 0 to 100 (higher is better and slower).
    progressive: An optional `bool`. Defaults to `False`.
      If True, create a JPEG that loads progressively (coarse to fine).
    optimize_size: An optional `bool`. Defaults to `False`.
      If True, spend CPU/RAM to reduce size with no quality change.
    chroma_downsampling: An optional `bool`. Defaults to `True`.
      See http://en.wikipedia.org/wiki/Chroma_subsampling.
    density_unit: An optional `string` from: `"in", "cm"`. Defaults to `"in"`.
      Unit used to specify `x_density` and `y_density`:

      pixels per inch (`'in'`) or centimeter (`'cm'`).
    x_density: An optional `int`. Defaults to `300`.
      Horizontal pixels per density unit.
    y_density: An optional `int`. Defaults to `300`.
      Vertical pixels per density unit.
    xmp_metadata: An optional `string`. Defaults to `""`.
      If not empty, embed this XMP metadata in the image header.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `string`.

        side is less than `min_size`.

        Inputs:

        `scores`: A 4D tensor of shape [Batch, Height, Width, Num Anchors] containing the scores per anchor at given position

        `bbox_deltas`: is a tensor of shape [Batch, Height, Width, 4 x Num Anchors] boxes encoded to each anchor

        `anchors`: A 1D tensor of shape [4 x Num Anchors], representing the anchors.

        Outputs:

        `roi_probabilities`: probability scores of each roi in 'rois', a 2D tensor of shape [Batch,post_nms_topn], padded with 0 if needed, sorted by scores.

  Args:
    scores: A `Tensor` of type `float32`.
      A 4-D float tensor of shape `[num_images, height, width, num_achors]` containing scores of the boxes for given anchors, can be unsorted.
    bbox_deltas: A `Tensor` of type `float32`.
      A 4-D float tensor of shape `[num_images, height, width, 4 x num_anchors]`. encoding boxes with respec to each anchor.

      Coordinates are given in the form [dy, dx, dh, dw].
    image_info: A `Tensor` of type `float32`.

  r"""Greedily selects a subset of bounding boxes in descending order of score,

  pruning away boxes that have high intersection-over-union (IOU) overlap

  with previously selected boxes.  Bounding boxes with score less than

  `score_threshold` are removed.  Bounding boxes are supplied as

  [y1, x1, y2, x2], where (y1, x1) and (y2, x2) are the coordinates of any

  diagonal pair of box corners and the coordinates can be provided as normalized

  (i.e., lying in the interval [0, 1]) or absolute.  Note that this algorithm

  is agnostic to where the origin is in the coordinate system and more

  generally is invariant to orthogonal transformations and translations

  of the coordinate system; thus translating or reflections of the coordinate

  system result in the same boxes being selected by the algorithm.

  The output of this operation is a set of integers indexing into the input

  collection of bounding boxes representing the selected boxes.  The bounding

  box coordinates corresponding to the selected indices can then be obtained

  using the `tf.gather operation`.  For example:

    selected_indices = tf.image.non_max_suppression_v2(

        boxes, scores, max_output_size, iou_threshold, score_threshold)

    selected_boxes = tf.gather(boxes, selected_indices)

  This op also supports a Soft-NMS (with Gaussian weighting) mode (c.f.

  Bodla et al, https://arxiv.org/abs/1704.04503) where boxes reduce the score

  of other overlapping boxes instead of directly causing them to be pruned.

  To enable this Soft-NMS mode, set the `soft_nms_sigma` parameter to be

  larger than 0.

  Args:
    boxes: A `Tensor`. Must be one of the following types: `half`, `float32`.
      A 2-D float tensor of shape `[num_boxes, 4]`.
    scores: A `Tensor`. Must have the same type as `boxes`.
      A 1-D float tensor of shape `[num_boxes]` representing a single

      score corresponding to each box (each row of boxes).
    max_output_size: A `Tensor` of type `int32`.
      A scalar integer tensor representing the maximum number of

      boxes to be selected by non max suppression.
    iou_threshold: A `Tensor`. Must have the same type as `boxes`.
      A 0-D float tensor representing the threshold for deciding whether

      boxes overlap too much with respect to IOU.
    score_threshold: A `Tensor`. Must have the same type as `boxes`.
      A 0-D float tensor representing the threshold for deciding when to remove

      boxes based on score.
    soft_nms_sigma: A `Tensor`. Must have the same type as `boxes`.
      A 0-D float tensor representing the sigma parameter for Soft NMS; see Bodla et

      al (c.f. https://arxiv.org/abs/1704.04503).  When `soft_nms_sigma=0.0` (which

      is default), we fall back to standard (hard) NMS.
    pad_to_max_output_size: An optional `bool`. Defaults to `False`.
      If true, the output `selected_indices` is padded to be of length

      `max_output_size`. Defaults to false.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (selected_indices, selected_scores, valid_outputs).

    selected_indices: A `Tensor` of type `int32`.
    selected_scores: A `Tensor`. Has the same type as `boxes`.

  Input images can be of different types but output images are always float.

  To guarantee an output range, for example `[0.0, 1.0]`, apply

  `tf.clip_by_value` to the output.

  

  Each output pixel is computed by first transforming the pixel's footprint into

  the input tensor and then averaging the pixels that intersect the footprint. An

  input pixel's contribution to the average is weighted by the fraction of its

  area that intersects the footprint.  This is the same as OpenCV's INTER_AREA.

  r"""Generate a single randomly distorted bounding box for an image.

  Bounding box annotations are often supplied in addition to ground-truth labels

  in image recognition or object localization tasks. A common technique for

  training such a system is to randomly distort an image while preserving

  its content, i.e. *data augmentation*. This Op outputs a randomly distorted

  localization of an object, i.e. bounding box, given an `image_size`,

  `bounding_boxes` and a series of constraints.

  

  The output of this Op is a single bounding box that may be used to crop the

  original image. The output is returned as 3 tensors: `begin`, `size` and

  `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the

  image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize

  what the bounding box looks like.

  

  Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The

  bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and

  height of the underlying image.

  

  For example,

  

  ```python

      # Generate a single distorted bounding box.

      begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(

          tf.shape(image),

          bounding_boxes=bounding_boxes)

  

      # Draw the bounding box in an image summary.

      image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),

                                                    bbox_for_draw)

      tf.summary.image('images_with_box', image_with_box)

  

      # Employ the bounding box to distort the image.

      distorted_image = tf.slice(image, begin, size)

  ```

  

  Note that if no bounding box information is available, setting

  `use_image_if_no_bounding_boxes = true` will assume there is a single implicit

  bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is

  false and no bounding boxes are supplied, an error is raised.

  Args:
    image_size: A `Tensor`. Must be one of the following types: `uint8`, `int8`, `int16`, `int32`, `int64`.
      1-D, containing `[height, width, channels]`.
    bounding_boxes: A `Tensor` of type `float32`.
      3-D with shape `[batch, N, 4]` describing the N bounding boxes

      associated with the image.
    seed: An optional `int`. Defaults to `0`.
      If either `seed` or `seed2` are set to non-zero, the random number

      generator is seeded by the given `seed`.  Otherwise, it is seeded by a random

      seed.
    seed2: An optional `int`. Defaults to `0`.
      A second seed to avoid seed collision.
    min_object_covered: An optional `float`. Defaults to `0.1`.
      The cropped area of the image must contain at least this

      fraction of any bounding box supplied. The value of this parameter should be

      non-negative. In the case of 0, the cropped area does not need to overlap

      any of the bounding boxes supplied.
    aspect_ratio_range: An optional list of `floats`. Defaults to `[0.75, 1.33]`.
      The cropped area of the image must have an aspect ratio =

      width / height within this range.
    area_range: An optional list of `floats`. Defaults to `[0.05, 1]`.
      The cropped area of the image must contain a fraction of the

      supplied image within this range.
    max_attempts: An optional `int`. Defaults to `100`.
      Number of attempts at generating a cropped region of the image

      of the specified constraints. After `max_attempts` failures, return the entire

      image.
    use_image_if_no_bounding_boxes: An optional `bool`. Defaults to `False`.
      Controls behavior if no bounding boxes supplied.

      If true, assume an implicit bounding box covering the whole input. If false,

      raise an error.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (begin, size, bboxes).

    begin: A `Tensor`. Has the same type as `image_size`.
    size: A `Tensor`. Has the same type as `image_size`.
    bboxes: A `Tensor` of type `float32`.

  r"""Generate a single randomly distorted bounding box for an image.

  Bounding box annotations are often supplied in addition to ground-truth labels

  in image recognition or object localization tasks. A common technique for

  training such a system is to randomly distort an image while preserving

  its content, i.e. *data augmentation*. This Op outputs a randomly distorted

  localization of an object, i.e. bounding box, given an `image_size`,

  `bounding_boxes` and a series of constraints.

  

  The output of this Op is a single bounding box that may be used to crop the

  original image. The output is returned as 3 tensors: `begin`, `size` and

  `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the

  image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize

  what the bounding box looks like.

  

  Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The

  bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and

  height of the underlying image.

  

  For example,

  

  ```python

      # Generate a single distorted bounding box.

      begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(

          tf.shape(image),

          bounding_boxes=bounding_boxes)

  

      # Draw the bounding box in an image summary.

      image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),

                                                    bbox_for_draw)

      tf.summary.image('images_with_box', image_with_box)

  

      # Employ the bounding box to distort the image.

      distorted_image = tf.slice(image, begin, size)

  ```

  

  Note that if no bounding box information is available, setting

  `use_image_if_no_bounding_boxes = true` will assume there is a single implicit

  bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is

  false and no bounding boxes are supplied, an error is raised.

  Args:
    image_size: A `Tensor`. Must be one of the following types: `uint8`, `int8`, `int16`, `int32`, `int64`.
      1-D, containing `[height, width, channels]`.
    bounding_boxes: A `Tensor` of type `float32`.
      3-D with shape `[batch, N, 4]` describing the N bounding boxes

      associated with the image.
    min_object_covered: A `Tensor` of type `float32`.
      The cropped area of the image must contain at least this

      fraction of any bounding box supplied. The value of this parameter should be

      non-negative. In the case of 0, the cropped area does not need to overlap

      any of the bounding boxes supplied.
    seed: An optional `int`. Defaults to `0`.
      If either `seed` or `seed2` are set to non-zero, the random number

      generator is seeded by the given `seed`.  Otherwise, it is seeded by a random

      seed.
    seed2: An optional `int`. Defaults to `0`.
      A second seed to avoid seed collision.
    aspect_ratio_range: An optional list of `floats`. Defaults to `[0.75, 1.33]`.
      The cropped area of the image must have an aspect ratio =

      width / height within this range.
    area_range: An optional list of `floats`. Defaults to `[0.05, 1]`.
      The cropped area of the image must contain a fraction of the

      supplied image within this range.
    max_attempts: An optional `int`. Defaults to `100`.
      Number of attempts at generating a cropped region of the image

      of the specified constraints. After `max_attempts` failures, return the entire

      image.
    use_image_if_no_bounding_boxes: An optional `bool`. Defaults to `False`.
      Controls behavior if no bounding boxes supplied.

      If true, assume an implicit bounding box covering the whole input. If false,

      raise an error.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (begin, size, bboxes).

    begin: A `Tensor`. Has the same type as `image_size`.
    size: A `Tensor`. Has the same type as `image_size`.
    bboxes: A `Tensor` of type `float32`.

  r"""Generate a randomly distorted bounding box for an image deterministically.

  Bounding box annotations are often supplied in addition to ground-truth labels

  in image recognition or object localization tasks. A common technique for

  training such a system is to randomly distort an image while preserving its

  content, i.e. *data augmentation*. This Op, given the same `seed`,

  deterministically outputs a randomly distorted localization of an object, i.e.

  bounding box, given an `image_size`, `bounding_boxes` and a series of

  constraints.

  

  The output of this Op is a single bounding box that may be used to crop the

  original image. The output is returned as 3 tensors: `begin`, `size` and

  `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the

  image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize

  what the bounding box looks like.

  

  Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The

  bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and

  the height of the underlying image.

  

  The output of this Op is guaranteed to be the same given the same `seed` and is

  independent of how many times the function is called, and independent of global

  seed settings (e.g. `tf.random.set_seed`).

  

  Example usage:

  

  >>> image = np.array([[[1], [2], [3]], [[4], [5], [6]], [[7], [8], [9]]])

  >>> bbox = tf.constant(

  ...   [0.0, 0.0, 1.0, 1.0], dtype=tf.float32, shape=[1, 1, 4])

  >>> seed = (1, 2)

  >>> # Generate a single distorted bounding box.

  >>> bbox_begin, bbox_size, bbox_draw = (

  ...   tf.image.stateless_sample_distorted_bounding_box(

  ...     tf.shape(image), bounding_boxes=bbox, seed=seed))

  >>> # Employ the bounding box to distort the image.

  >>> tf.slice(image, bbox_begin, bbox_size)

  <tf.Tensor: shape=(2, 2, 1), dtype=int64, numpy=

  array([[[1],

          [2]],

         [[4],

          [5]]])>

  >>> # Draw the bounding box in an image summary.

  >>> colors = np.array([[1.0, 0.0, 0.0], [0.0, 0.0, 1.0]])

  >>> tf.image.draw_bounding_boxes(

  ...   tf.expand_dims(tf.cast(image, tf.float32),0), bbox_draw, colors)

  <tf.Tensor: shape=(1, 3, 3, 1), dtype=float32, numpy=

  array([[[[1.],

           [1.],

           [3.]],

          [[1.],

           [1.],

           [6.]],

          [[7.],

           [8.],

           [9.]]]], dtype=float32)>

  

  Note that if no bounding box information is available, setting

  `use_image_if_no_bounding_boxes = true` will assume there is a single implicit

  bounding box covering the whole image. If `use_image_if_no_bounding_boxes` is

  false and no bounding boxes are supplied, an error is raised.

  Args:
    image_size: A `Tensor`. Must be one of the following types: `uint8`, `int8`, `int16`, `int32`, `int64`.
      1-D, containing `[height, width, channels]`.
    bounding_boxes: A `Tensor` of type `float32`.
      3-D with shape `[batch, N, 4]` describing the N bounding boxes

      associated with the image.
    min_object_covered: A `Tensor` of type `float32`.
      The cropped area of the image must contain at least this

      fraction of any bounding box supplied. The value of this parameter should be

      non-negative. In the case of 0, the cropped area does not need to overlap

      any of the bounding boxes supplied.
    seed: A `Tensor`. Must be one of the following types: `int32`, `int64`.
      1-D with shape `[2]`. The seed to the random number generator. Must have dtype

      `int32` or `int64`. (When using XLA, only `int32` is allowed.)
    aspect_ratio_range: An optional list of `floats`. Defaults to `[0.75, 1.33]`.
      The cropped area of the image must have an aspect ratio =

      width / height within this range.
    area_range: An optional list of `floats`. Defaults to `[0.05, 1]`.
      The cropped area of the image must contain a fraction of the

      supplied image within this range.
    max_attempts: An optional `int`. Defaults to `100`.
      Number of attempts at generating a cropped region of the image

      of the specified constraints. After `max_attempts` failures, return the entire

      image.
    use_image_if_no_bounding_boxes: An optional `bool`. Defaults to `False`.
      Controls behavior if no bounding boxes supplied.

      If true, assume an implicit bounding box covering the whole input. If false,

      raise an error.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (begin, size, bboxes).

    begin: A `Tensor`. Has the same type as `image_size`.
    size: A `Tensor`. Has the same type as `image_size`.
    bboxes: A `Tensor` of type `float32`.
