CUHK Crowd Dataset

Description

a. The whole 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.
  • The COPYRIGHT of the videos (with watermark) belongs to GettyImages and Pond5 respectively.

b. Dataset used in paper:

  • In our 14'cvpr paper, we take only 30 frames from each clip to implement and evaluate our approach.
  • The frame for group detection can be found in dataset_info, and the groundtruth of 300 group detection can be downloaded from here.
  • Dataset_info ("video_gt") also provides the groundtruth of video classes corresponding to our defined 8 classes in the cvpr paper.
  • You can get 215 independent scene from dataset_info ("scene_number"), different number means different scenes.
  • These data can only be used for academic research purposes.
