MatAnyone is an open source tool for video keying developed by the S-Lab research team at Nanyang Technological University in Singapore and released on the GitHub platform. The project uses consistent memory propagation techniques and memory fusion modules to efficiently handle target-specific keying tasks in complex backgrounds. Its core advantage is to maintain semantic stability while accurately retaining object boundary details, especially suitable for film and television post-production, virtual background replacement and other professional scenarios.
The tool was introduced in 2025 by researchers such as Peiqing Yang and is licensed under the NTU S-Lab License 1.0, which allows users to freely use, modify, and distribute the code.MatAnyone's innovativeness has led to widespread interest in academia and the open source community.
