YOLO Liga
Sponsor Detection in Football Broadcasts
Developed a computer vision system to automatically detect sponsor advertisements in Portuguese football broadcasts, giving companies a data-driven way to measure their broadcast ROI.
Benchmarked YOLOv8 (s, m) and YOLO11 (m, l) on a dataset of 8,000+ images. YOLO11l, trained on a cloud NVIDIA RTX 6000 Ada, achieved a mAP50-95 of 0.73 — sufficient for production deployment in real-time stream analysis.

Use Case
This system enables sponsors and broadcasters to automatically measure advertisement visibility during live football matches. By detecting when and how long sponsor logos appear on screen, companies can quantify their broadcast ROI with precise, frame-by-frame data instead of relying on manual estimates.
