masks_to_boxes

torchvision.ops.masks_to_boxes(masks: Tensor) → Tensor

Compute the bounding boxes around the provided masks.

Returns a [N, 4] tensor containing bounding boxes. The boxes are in (x1, y1, x2, y2) format with 0 <= x1 < x2 and 0 <= y1 < y2.

Parameters:

masks (Tensor[N, H, W]) – masks to transform where N is the number of masks and (H, W) are the spatial dimensions.

Returns:

bounding boxes

Return type:

Tensor[N, 4]
