Breaking Changes
In order to support the visualization for Panoptic Segmentation, the num_classes can not be None when using the get_palette function to determine whether to use the panoptic palette.
Highlights
- Support MaskFormer: Per-Pixel Classification is Not All You Need for Semantic Segmentation (#7212)
- Support DyHead: Dynamic Head: Unifying Object Detection Heads with Attentions (#6823)
- Release a good recipe of using ResNet in object detectors pre-trained by ResNet Strikes Back, which consistently brings about 3~4 mAP improvements over RetinaNet, Faster/Mask/Cascade Mask R-CNN (#7001)
- Support Open Images Dataset (#6331)
- Support TIMM backbone: PyTorch Image Models (#7020)
