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 1.6+.

Major features

• Modular Design

  We decompose the detection framework into different components and one can easily construct a customized object detection framework by combining different modules.

• Support of multiple tasks out of box

  The toolbox directly supports multiple detection tasks such as object detection, instance segmentation, panoptic segmentation, and semi-supervised object detection.

• High efficiency

  All basic bbox and mask operations run on GPUs. The training speed is faster than or comparable to other codebases, including Detectron2, maskrcnn-benchmark and SimpleDet.

• State of the art

  The toolbox stems from the codebase developed by the MMDet team, who won COCO Detection Challenge in 2018, and we keep pushing it forward.

Apart from MMDetection, we also released MMEngine for model training and MMCV for computer vision research, which are heavily depended on by this toolbox.

What's New

v3.0.0rc0 was released in 31/8/2022:

• Unifies interfaces of all components based on MMEngine.
• Faster training and testing speed with complete support of mixed precision training.
• Refactored and more flexible architecture.
• Provides more strong baselines and a general semi-supervised object detection framework. See tutorial of semi-supervised detection.
• Allows any kind of single-stage model as an RPN in a two-stage model. See tutorial.
