- torchvision.ops.complete_box_iou_loss(boxes1: Tensor, boxes2: Tensor, reduction: str = 'none', eps: float = 1e-07) Tensor ¶
Gradient-friendly IoU loss with an additional penalty that is non-zero when the boxes do not overlap. This loss function considers important geometrical factors such as overlap area, normalized central point distance and aspect ratio. This loss is symmetric, so the boxes1 and boxes2 arguments are interchangeable.
Both sets of boxes are expected to be in
(x1, y1, x2, y2)format with
0 <= x1 < x2and
0 <= y1 < y2, and The two boxes should have the same dimensions.
boxes1 – (Tensor[N, 4] or Tensor) first set of boxes
boxes2 – (Tensor[N, 4] or Tensor) second set of boxes
reduction – (string, optional) Specifies the reduction to apply to the output:
'none': No reduction will be applied to the output.
'mean': The output will be averaged.
'sum': The output will be summed. Default:
eps – (float): small number to prevent division by zero. Default: 1e-7
Loss tensor with the reduction option applied.
