NOTE ON MODELS AND THIRD-PARTY COMPONENTS

The MIT license above applies only to the source code in this repository. It
does NOT cover:

  * Machine-learning model weights (the ONNX files in models/). These weights
    are the property of their respective authors and are governed by their own
    licenses, not by the MIT license above. The models — including the
    InsightFace "buffalo" packs (ArcFace / SCRFD), YuNet, and LVFace — are
    redistributed here for convenience under those upstream licenses. Several,
    notably the InsightFace models, are licensed for NON-COMMERCIAL RESEARCH
    USE ONLY. You are responsible for reviewing and complying with each model's
    license before use.

  * Third-party libraries this software links against (OpenCV, ONNX Runtime,
    FFmpeg, TensorRT/CUDA, nlohmann/json, nanobind, and others), each of which
    carries its own license.
