EP3761221A1
PEDESTRIAN RE-IDENTIFICATION METHOD AND APPARATUS
Publication/Patent Number: EP3761221A1 Publication Date: 2021-01-06 Application Number: 19792513.4 Filing Date: 2019-04-26 Inventor: Wu, Jiangxu   Zhang, Weihua   Zhang, Hongguang   Peng, Ganglin   Kong, Leifeng   Wu, Yuefeng   Yong, Xinghui   Li, Fan   Assignee: Beijing Jingdong Shangke Information Technology Co., Ltd.   Beijing Jingdong Century Trading Co., Ltd.   IPC: G06K9/00 Abstract: The present disclosure provides a pedestrian re-identification method and apparatus. The pedestrian re-identification apparatus detects a pedestrian to be identified in a specified video frame, and within a specified time period before the capture time of the specified video frame, extracts all pedestrians appearing in the captured video frame and taking them to be historical pedestrians; calculating the feature distances between the pedestrian to be identified and the historical pedestrians; in order of feature distance, from small to large, extracting historical pedestrian identifications corresponding to a predetermined number of feature distances, and clustering the extracted historical pedestrian identifications so as to re-identify the pedestrians to be identified. The present disclosure effectively suppresses external noise interference and improves the success rate of pedestrian re-identification.

US2021201009A1
PEDESTRIAN RE-IDENTIFICATION METHOD AND APPARATUS
Publication/Patent Number: US2021201009A1 Publication Date: 2021-07-01 Application Number: 17/044,578 Filing Date: 2019-04-26 Inventor: Wu, Jiangxu   Zhang, Weihua   Zhang, Hongguang   Peng, Ganglin   Kong, Leifeng   Wu, Yuefeng   Yong, Xinghui   Li, Fan   Assignee: BEIJING JINGDONG SHANGKE INFORMATION TECHNOLOGY CO., LTD.   BEIJING JINGDONG CENTURY TRADING CO., LTD.   IPC: G06K9/00 Abstract: The present disclosure provides a pedestrian re-identification method and apparatus. The pedestrian re-identification apparatus detects a pedestrian to be identified in a preset video frame, extract all pedestrians appearing in video frames shot in a preset time period before a shooting time of the preset video frame as historical pedestrians, calculate a feature distance between the pedestrian to be identified and each historical pedestrian of the historical pedestrians, extract historical pedestrian IDs corresponding to a preset number of the feature distances in ascending order of the feature distances, and cluster the historical pedestrian IDs to re-identify the pedestrian to be identified.
