A new low illumination pedestrian sequence (LIPS) dataset is collected under night scenes in campus of Wuhan University. The dataset includes 90021 images of 100 pedestrians captured by two non-overlapping cameras. The length of each image sequence ranges from 193 to 833 frames,with an average number of 450 for each person at each camera. Many images are captured under very low illumination. Most of persons are occluded by other objects, e.g., other pedestrians, cars or trees.
