tensorflow:: ops:: CropAndResizeGradBoxes
#include <image_ops.h>
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]. Bothimage_heightandimage_widthneed to be positive. - boxes: A 2-D tensor of shape
[num_boxes, 4]. Thei-th row of the tensor specifies the coordinates of a box in thebox_ind[i]image and is specified in normalized coordinates[y1, x1, y2, x2]. A normalized coordinate value ofyis mapped to the image coordinate aty * (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 useextrapolation_valueto extrapolate the input image values. - box_ind: A 1-D tensor of shape
[num_boxes]with int32 values in[0, batch). The value ofbox_ind[i]specifies the image that thei-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].
