Video Copyright Detection Algorithm: Competition Solution Overview
The Hulu Brothers’ competition solution tackles large‑scale video copyright detection by extracting I‑frames, encoding them with ResNet‑18 CNN features, performing approximate nearest‑neighbor search and ORB re‑ranking to match queries to reference videos, then linearly interpolating frame correspondences for precise temporal alignment, achieving high precision, recall and F1 scores.
