Introduction

MMDetection is an open source object detection toolbox based on PyTorch. It is a part of the OpenMMLab project.

The master branch works with PyTorch 1.5+.

Apart from MMDetection, we also released a library mmcv for computer vision research, which is heavily depended on by this toolbox.

What’s New

💎 Stable version

2.28.2 was released in 27/2/2023:

• Fixed some known documentation, configuration and linking error issues

Please refer to changelog.md for details and release history.

For compatibility changes between different versions of MMDetection, please refer to compatibility.md.

🌟 Preview of 3.x version

Highlight

We are excited to announce our latest work on real-time object recognition tasks, RTMDet, a family of fully convolutional single-stage detectors. RTMDet not only achieves the best parameter-accuracy trade-off on object detection from tiny to extra-large model sizes but also obtains new state-of-the-art performance on instance segmentation and rotated object detection tasks. Details can be found in the technical report. Pre-trained models are here.

A brand new version of MMDetection v3.0.0rc6 was released in 27/2/2023:

• Support Boxinst, Objects365 Dataset, and Separated and Occluded COCO metric
• Support ConvNeXt-V2, DiffusionDet, and inference of EfficientDet and Detic in Projects
• Refactor DETR series and support Conditional-DETR, DAB-DETR, and DINO
• Support DetInferencer, Test Time Augmentation, and auto import modules from registry
• Support RTMDet-Ins ONNXRuntime and TensorRT deployment
• Support calculating FLOPs of detectors

Find more new features in 3.x branch. Issues and PRs are welcome!
