# SAM2Matting Demo

This Space demonstrates **SAM2Matting** — a generalized matting framework that
decouples high-level tracking from dedicated low-level matting. It takes an
image and a rough foreground mask as input and produces a high-quality alpha
matte with fine detail (hair, fur, translucent edges).

## Model
