# box_iou

torchvision.ops.box_iou(boxes1: Tensor, boxes2: Tensor) → Tensor

  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]
