Calculates IoAs (intersection over area) between proposal and ground truth boxes.
tfm.vision.box_ops.bbox_intersection_over_area(
boxes, gt_boxes
)
Some boxes
or gt_boxes
may have been padded. The returned iou
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, M, 4]. This tensor might
have paddings with a negative value.
|
Returns |
ioa
|
a tensor with as a shape of [batch_size, N, M].
