2021 AI City Challenge Track 5: Natural Language-Based Vehicle Retrieval

Natural language (NL) description offers another useful way to specify vehicle track queries. In this new Challenge Track, participating teams will perform vehicle retrieval given single-camera tracks and corresponding NL descriptions of the targets. The performance of the retrieval task will be evaluated using standard metrics of retrieval tasks while considering ambiguity caused by similar vehicle types, colors, and motion types.
