tensorflow::ops::CropAndResizeGradBoxes

Computes the gradient of the crop_and_resize op wrt the input boxes tensor.

Summary

Args:

• scope: A Scope object
• grads: A 4-D tensor of shape [num_boxes, crop_height, crop_width, depth].
• image: A 4-D tensor of shape [batch, image_height, image_width, depth]. Both image_height and image_width need to be positive.
• boxes: 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 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.

Optional attributes (see Attrs):

• method: A string specifying the interpolation method. Only 'bilinear' is supported for now.

Returns:

• Output: A 2-D tensor of shape [num_boxes, 4].
