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.

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.
