MODNet portrait matting model

The Portrait Cutout tool loads the reviewed Xenova/modnet revision fa2fa54 ONNX model from Hugging Face. The model and its upstream code are released under the Apache License 2.0.

Collayz pins that full immutable model revision so weights, configuration, and license metadata cannot change independently of an application release.

Upstream project: MODNet by Zhanghan Ke and contributors.

Scope and limitations

MODNet is intended for portrait matting. It is not represented as a general-purpose remover for arbitrary products, animals, or scenes. Results vary with lighting, subject/background contrast, fine hair, transparency, and device capabilities, and should be reviewed before publication.
