Support for various datasets
Video datasets have emerging throughout the recent years and have greatly fostered the devlopment of this field. MMAction provides tools to deal with various datasets.
Support for multiple action understanding frameworks
MMAction implements popular frameworks for action understanding:
For action recognition, various algorithms are implemented, including TSN, I3D, SlowFast, R(2+1)D, CSN.
For temporal action detection, we implement SSN.
For spatial temporal atomic action detection, a Fast-RCNN baseline is provided.
Modular design
The tasks in human action understanding share some common aspects such as backbones, and long-term and short-term sampling schemes. Also, tasks can benefit from each other. For example, a better backbone for action recognition will bring performance gain for action detection. Modular design enables us to view action understanding in a more integrated perspective.

Updates
v0.1.0 (19/06/2019)
MMAction is online!
v0.2.0 (15/03/2020)
We build a diversified modelzoo for action recognition, which include popular algorithms (TSN, I3D, SlowFast, R(2+1)D, CSN). The performance is aligned with or better than the original papers.
Model zoo
Results and reference models are available in the model zoo.
Installation
Please refer to INSTALL.md for installation.
Update: for Docker installation, Please refer to DOCKER.md for using docker for this project.
Data preparation
