MMDetection: OpenMMLab Detection Toolbox and Benchmark

MMDetection is an open-source object detection toolbox based on PyTorch, part of the OpenMMLab project. It provides a comprehensive collection of detection, instance segmentation, and object grounding algorithms, along with a benchmark for various computer vision tasks. Currently at version 3.3.0, it features frequent updates, including state-of-the-art models like Grounding DINO and various Transformer-based detectors, and integrates closely with other OpenMMLab libraries like MMEngine and MMCV.
