Occluded Cloth-Changing Person Re-Identification

Cloth-changing person re-identification aims to retrieve and identify spe-cific pedestrians by using cloth-irrelevant features in person cloth-changing scenarios. However, pedestrian images captured by surveillance probes usually contain occlusions in real-world scenarios. The perfor-mance of existing cloth-changing re-identification methods is significantly degraded due to the reduction of discriminative cloth-irrelevant features caused by occlusion. We define cloth-changing person re-identification in occlusion scenarios as occluded cloth-changing person re-identification (Occ-CC-ReID), and to the best of our knowledge, we are the first to pro-pose occluded cloth-changing person re-identification as a new task. We constructed two occluded cloth-changing person re-identification datasets for different occlusion scenarios: Occluded-PRCC and Occluded-LTCC. The datasets can be obtained from the following link: https://github.com/1024AILab/Occluded-Cloth-Changing-Person- Re-Identification.
