Calculates the GIOU between proposal and ground truth boxes.
tfm.vision.box_ops.bbox_generalized_overlap(
boxes, gt_boxes
)
The generalized intersection of union is an adjustment of the traditional IOU
metric which provides continuous updates even for predictions with no overlap.
This metric is defined in https://giou.stanford.edu/GIoU.pdf Note, some
gt_boxes
may have been padded. The returned giou
tensor for these boxes
will be -1.
Args |
boxes
|
a Tensor with a shape of [batch_size, N, 4]. N is the number of
proposals before groundtruth assignment (e.g., rpn_post_nms_topn). The
last dimension is the pixel coordinates in [ymin, xmin, ymax, xmax] form.
|
gt_boxes
|
a Tensor with a shape of [batch_size, max_num_instances, 4].
This tensor may have paddings with a negative value and will also be in
the [ymin, xmin, ymax, xmax] format.
|
Returns |
giou
|
a Tensor with as a shape of [batch_size, N, max_num_instances].
