Args
grads	A Tensor of type float32. A 4-D tensor of shape [num_boxes, crop_height, crop_width, depth].
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 ofy 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 useextrapolation_valueto extrapolate the input image values.
box_ind	ATensorof typeint32. 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.
image_size	ATensorof typeint32. A 1-D tensor with value[batch, image_height, image_width, depth]containing the original image size. Bothimage_heightandimage_widthneed to be positive.
T	A `tf.DType` from:tf.float32, tf.half, tf.float64.
method	An optionalstringfrom:"bilinear", "nearest". Defaults to"bilinear". A string specifying the interpolation method. Only 'bilinear' is supported for now.
name`	A name for the operation (optional).

Returns
A Tensor of type T.
