mmcv.ops.convex_giou¶
- mmcv.ops.convex_giou(pointsets: torch.Tensor, polygons: torch.Tensor) → Tuple[torch.Tensor, torch.Tensor][source]¶
Return generalized intersection-over-union (Jaccard index) between point sets and polygons.
- Parameters
pointsets (torch.Tensor) – It has shape (N, 18), indicating (x1, y1, x2, y2, …, x9, y9) for each row.
polygons (torch.Tensor) – It has shape (N, 8), indicating (x1, y1, x2, y2, x3, y3, x4, y4) for each row.
- Returns
The first element is the gious between point sets and polygons with the shape (N,). The second element is the gradient of point sets with the shape (N, 18).
- Return type
