Core Technology of Video Content Understanding — Technical Practice of Partial Re-ID in Video Inspection
Person Re-identification (re-ID) is a challenging real‑world task that aims to match the same person captured by different cameras from various viewpoints.
In video content, re‑ID algorithms can match characters across different shots, obtaining complete appearance information, and deriving metrics such as character presence, interaction, and storyline that reflect video quality.
Because content videos contain extensive manual editing, scene scheduling, and shot switching, how can visual models be specifically improved and optimized for these complexities? This talk uses the Partial‑ReID algorithm for episodic scenes as an example to detail the technical practice of video content creation understanding.
