Oct 2025 — PresentBuilds production video analytics, including seatbelt detection, face analysis, liveness checks, and face tracking improvements.
• Built a two-stage hybrid pipeline for driver seatbelt detection: YOLO-World and SAM3 localise the driver region in real time and filter frames at the edge, then verified triggers go to a Qwen-VL vision-language model served on vLLM, whose visual reasoning keeps false positives low. • Designed and shipped a multi-task face analysis model: six attribute heads (age, gender, emotion, beard, glasses, mask) trained on shared ArcFace features and merged with the backbone into a single ONNX graph, so one forward pass returns the identity embedding and all attributes.
