Koolook Matte — NOTICE
======================

The CODE in this pack is licensed under GPL-3.0 (see the repository LICENSE) and
is an ORIGINAL, independent implementation — it does not incorporate third-party
wrapper code.

Method credit
-------------
This pack implements the method described in:
  "VideoMaMa: Mask-Guided Video Matting via Generative Prior" (CVPR 2026),
  cvlab-kaist — https://github.com/cvlab-kaist/VideoMaMa
The method, the original reference code, and the trained weights are the work of
those authors. This project re-implements the (published) inference method using
the standard `diffusers` API and adds its own windowing / focus-crop tooling.

Model weights (NOT bundled or redistributed — loaded at runtime)

licenses. This pack downloading/loading a model does not grant you any rights

Technique note
--------------
The temporal sliding-window batching and the subject bounding-box crop/paste
implemented here are standard, well-known techniques, written independently for
this pack.
