CUHK Crowd Dataset

474 video clips from 215 crowded scenes. Each clip with the extracted trajectories by gKLT tracker is preprocessed by deleting short trajectories, stationary points, and some errors. Details of dataset can be found in dataset_info. It contains video name, video length, video size, video source, video t0 (the frame for group detection evaluation), group detection (300 group detection used in our cvpr paper), video_gt (video classes groundtruth), and scene number. (You can also choose any frame to do group detection. The frame list in video_info_t0 is just what we use in our cvpr paper.) These data can only be used for academic research purposes.
