This chapter introduces you to the framework of MMDetection, and provides links to detailed tutorials about MMDetection.

What is MMDetection

image

MMDetection is an object detection toolbox that contains a rich set of object detection, instance segmentation, and panoptic segmentation methods as well as related components and modules, and below is its whole framework:

MMDetection consists of 7 main parts, apis, structures, datasets, models, engine, evaluation and visualization.

  • apis provides high-level APIs for model inference.

  • structures provides data structures like bbox, mask, and DetDataSample.

  • datasets supports various dataset for object detection, instance segmentation, and panoptic segmentation.

    • transforms contains a lot of useful data augmentation transforms.

    • samplers defines different data loader sampling strategy.

  • models is the most vital part for detectors and contains different components of a detector.

    • detectors defines all of the detection model classes.

    • data_preprocessors is for preprocessing the input data of the model.

    • backbones contains various backbone networks.

    • necks contains various neck components.

    • dense_heads contains various detection heads that perform dense predictions.

    • roi_heads contains various detection heads that predict from RoIs.

    • seg_heads contains various segmentation heads.

    • losses contains various loss functions.

    • task_modules provides modules for detection tasks. E.g. assigners, samplers, box coders, and prior generators.

    • layers provides some basic neural network layers.

  • engine is a part for runtime components.

    • runner provides extensions for MMEngine’s runner.

    • schedulers provides schedulers for adjusting optimization hyperparameters.

    • optimizers provides optimizers and optimizer wrappers.

    • hooks provides various hooks of the runner.

  • evaluation provides different metrics for evaluating model performance.

  • visualization is for visualizing detection results.
