GAIT-BASED IDENTITY RECOGNITION METHOD AND APPARATUS, AND ELECTRONIC DEVICE

摘要

A gait-based identity recognition method and apparatus, and an electronic device, relating to the technical field of identity recognition, and solving the problem in the prior art of the accuracy of gait-based identity recognition methods in multiple pedestrian scenarios. The method comprises: implementing pedestrian detection, tracking, and pedestrian re-recognition for a video image sequence to determine target pedestrians in the video image sequence (110); determining a silhouette image sequence of the target pedestrians (120); on the basis of the silhouette image sequence of each target pedestrian, respectively acquiring a gait energy map of the target pedestrian (130); and, on the basis of the gait energy map of the target pedestrians, implementing identity recognition of the target pedestrians (140). The present method incorporates pedestrian detection, tracking, and pedestrian re-recognition technology to implement recognition of the same or different target pedestrians in a video image sequence, increasing the accuracy of the recognition of target pedestrians in a video image sequence, and thereby increasing the accuracy of gait-based identity recognition in multi-person scenarios.
