mindspore.ops.IOU

class mindspore.ops.IOU(mode='iou')[source]

Calculates intersection over union for boxes.

Computes the intersection over union (IOU) or the intersection over foreground (IOF) based on the ground-truth and predicted regions.

Refer to mindspore.ops.iou() for more detail.

Supported Platforms:: Ascend GPU CPU

Examples

>>> iou = ops.IOU(mode='iou')
>>> anchor_boxes = Tensor(np.random.randint(1.0, 5.0, [3, 4]), mindspore.float16)
>>> gt_boxes = Tensor(np.random.randint(1.0, 5.0, [3, 4]), mindspore.float16)
>>> output = iou(anchor_boxes, gt_boxes)
>>> print(output.shape)
(3, 3)
