The 6th International Competition on Human Identification at a Distance (HID 2025) addresses the critical challenge of video-based human identification in noisy environments, where subtle inter-person distinctions must be captured under complex real-world conditions. This competition provides participants with preprocessed human body silhouettes and reference source code to facilitate algorithmic design. The competition also employs an automated evaluation system through CodaLab. The benchmark is the SUSTech-Competition dataset, a large gait database with 859 unique subjects.
