AddComment(R"DOC(
This operator is the second version of generate_proposals op to generate
bounding box proposals for Faster RCNN.
The proposals are generated for a list of images based on image
score 'Scores', bounding box regression result 'BboxDeltas' as
well as predefined bounding box shapes 'anchors'. Greedy
non-maximum suppression is applied to generate the final bounding
boxes.
The difference between this version and the first version is that the image
scale is no long needed now, so the input requires im_shape instead of im_info.
The change aims to unify the input for all kinds of objective detection
such as YOLO-v3 and Faster R-CNN. As a result, the min_size represents the
size on input image instead of original image which is slightly different
to before and will not effect the result.
