box_iou

torchvision.ops.box_iou(boxes1: Tensor, boxes2: Tensor) Tensor[source]

Return intersection-over-union (Jaccard index) between two sets of boxes.

Both sets of boxes are expected to be in (x1, y1, x2, y2) format with 0 <= x1 < x2 and 0 <= y1 < y2.

Parameters:
  • boxes1 (Tensor[N, 4]) – first set of boxes

  • boxes2 (Tensor[M, 4]) – second set of boxes

Returns:

the NxM matrix containing the pairwise IoU values for every element in boxes1 and boxes2

Return type:

Tensor[N, M]
