v3.2.0 was released in 12/10/2023:
1. Detection Transformer SOTA Model Collection
(1) Supported four updated and stronger SOTA Transformer models: DDQ, CO-DETR, AlignDETR, and H-DINO.
(2) Based on CO-DETR, MMDet released a model with a COCO performance of 64.1 mAP.
(3) Algorithms such as DINO support AMP/Checkpoint/FrozenBN, which can effectively reduce memory usage.
2. Comprehensive Performance Comparison between CNN and Transformer RF100 consists of a dataset collection of 100 real-world datasets, including 7 domains. It can be used to assess the performance differences of Transformer models like DINO and CNN-based algorithms under different scenarios and data volumes. Users can utilize this benchmark to quickly evaluate the robustness of their algorithms in various scenarios.
3. Support for GLIP and Grounding DINO fine-tuning, the only algorithm library that supports Grounding DINO fine-tuning The Grounding DINO algorithm in MMDet is the only library that supports fine-tuning. Its performance is one point higher than the official version, and of course, GLIP also outperforms the official version. We also provide a detailed process for training and evaluating Grounding DINO on custom datasets. Everyone is welcome to give it a try.
