generalized_box_iou

torchvision.ops.generalized_box_iou(boxes1: torch.Tensor, boxes2: torch.Tensor) → torch.Tensor

Return generalized 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 generalized IoU values for every element in boxes1 and boxes2

Return type

Tensor[N, M]
