Third-Party Notices

mHumanTrackAI stands on excellent open-source software. The components below are bundled or relied upon; their licenses and attributions are acknowledged here.
Important licensing flags
OmniParser / YOLOv8 (optional pointer-assist model) is AGPL-3.0 via Ultralytics — optional, and must be reviewed before bundling.
ZeroMQ / NetMQ are LGPL-3.0; compliance is met by shipping them as separate, replaceable libraries.
NVIDIA TensorRT / CUDA / cuDNN are proprietary and downloaded on demand (NVIDIA GPU systems only) under NVIDIA's own EULAs.

This software includes components from third parties, each governed by
their own license terms. This file reproduces the required notices.

⚠  IMPORTANT LICENSING FLAGS

  • OmniParser / YOLOv8 (optional pointer-assist vision component):
    The OmniParser icon-detection model is based on a fine-tuned YOLOv8
    model. Ultralytics YOLOv8 is licensed under AGPL-3.0, which requires
    that any application distributing it also be released as open source
    (or a commercial license purchased from Ultralytics). This component
    is OPTIONAL in mHumanTrackAI. If you distribute the app WITH this
    component, verify compliance with AGPL-3.0 or disable/replace it.

  • ZeroMQ / NetMQ (LGPL-3.0):
    mHumanTrackAI links dynamically to these libraries. LGPL-3.0 requires
    that end users can re-link against a modified version. Compliance is
    met by distributing NetMQ/pyzmq as separate, replaceable files (as
    produced by the project's build). Source available at the URLs below.

  • NVIDIA TensorRT / CUDA / cuDNN (proprietary):
    These components are downloaded on demand (NVIDIA GPU systems only) and
    are subject to NVIDIA's End User License Agreements. They are NOT
    redistributed by mHumanTrackAI directly; users accept NVIDIA's terms
    at download time. See the NVIDIA URLs listed below.
