New Features

Semantic Segmentation

• Release RTFormer, a real-time semantic segmentation model accepted by NeurIPS 2022. RTFormer combines the advantages of CNN and Transformer modules, and it achieves SOTA trade-off between performance and efficiency on several datasets.
• Release UHRNet, a semantic segmentation model. The segmentation accuracy of UHRNet is higher than that of HRNet on Cityscapes.
• Add 2 semantic segmentation models, i.e., TopFormer and MscaleOCRNet-PSA.
• Enhance model training module, i.e., training for single channel images, setting different learning rate for backbone and head.
• Add the tutorials of config preparation and training tricks.

Image Matting

• Release PP-MattingV2, a real-time human matting model with SOTA performance. Compared to previous models, the mean error is reduced by 17.91%, the inference speed is improved by 44.6% on GPU.
• Refine the tutorials and build the benchmark of Matting models.

3D Medical Segmentation

• Release MedicalSegV2, a superior 3D medical image segmentation solution.
• Release an intelligent annotation toolkit called EISeg-Med3D.
• Release an optimized implementation of nnUNet named nnUNet-D, which has model deployment module.
• Add 3 segmentation models, i.e., SwinUnet, TransUnet and nnFormer.
• Refine the tutorials, add detailed information of model zoo and model introduction.
