Attributions

RTEAM.ai's computer vision features are built on the open machine learning work listed below. We are grateful to its authors. Each entry preserves the title, author, source, and license that the respective license requires, and the list names every third-party model the analytics pipeline loads and no others.

PeopleNet

• Used for: Person detection (headcount, entries and exits)
• Author: NVIDIA Corporation
• Source: https://catalog.ngc.nvidia.com/orgs/nvidia/teams/tao/models/peoplenet
• License: NVIDIA Open Model License
• Note: Used as published (deployable_quantized_onnx_v2.6.3, INT8), compiled to a TensorRT engine for inference. The person class is used for counting. The face class is used to find the faces that the aggregate age, presentation and smile figures are counted from, and, where a venue switches facial recognition on, the faces read at its cameras for returning guests.

Tracking and video

Per-camera tracking uses RTEAM.ai's own motion-only tracker. No tracker model weights are used. Video is decoded by NVIDIA NVDEC through FFmpeg (LGPL-2.1-or-later, built from source as shared libraries and dynamically linked), and inference runs on the NVIDIA CUDA runtime and TensorRT, under NVIDIA's licenses. Results are sent with the Eclipse Paho MQTT C client. A second pipeline is kept as a fallback. It tracks with NvDCF, the discriminative correlation filter tracker included in the NVIDIA DeepStream SDK, with appearance-based re-identification disabled and motion-only re-association enabled, also without tracker model weights, and it runs on the NVIDIA DeepStream SDK, CUDA and TensorRT, under NVIDIA's licenses, and on GStreamer and GLib (LGPL-2.1, dynamically linked and unmodified).

Complete notices

The list above is the complete set of third-party models that the analytics pipeline loads. The full third-party notices, including the license texts for the runtime libraries, the Eclipse Public/Distribution License election for the MQTT client, and the SIL Open Font License covering the Geist typeface used on this page, ship with the software as THIRD_PARTY_NOTICES.md and are available on request.
