We propose SAM-PT, an extension of the Segment Anything Model (SAM) for zero-shot video segmentation. Our work offers a simple yet effective point-based perspective in video object segmentation research. For more details, refer to our paper.

Video Object Segmentation Demo

Annotators only provide a few points to denote the target object at the first video frame to get video segmentation results. Please visit our project page for more visualizations, including qualitative results on DAVIS 2017 videos and more Avatar clips.

Interactive Point-Based Video Segmentation

Annotators can interactively add or remove points to refine the segmentation results.
