Pedestrian search method, system and device based on bidirectional interaction network

Abstract

The invention belongs to the field of computer vision and pattern recognition, particularly relates to a pedestrian search method, system and device based on a bidirectional interaction network, and aims to solve the problem of low pedestrian search accuracy caused by the influence of scene information outside a bounding box on pedestrian features. The method of the system comprises the followingsteps: acquiring a tth frame image in an input video as an input image; normalizing the input image, and obtaining a search result of a pedestrian target to be searched through a pre-trained pedestrian search model; constructing the pedestrian search model based on a residual network, and adding a new classification layer in a classification regression layer of the residual network and is used forobtaining the identity classification probability of a pedestrian target. The accuracy of pedestrian search is improved.

Description

technical field [0001] The invention belongs to the fields of computer vision and pattern recognition, and in particular relates to a pedestrian search method, system and device based on a two-way interactive network. Background technique [0002] The purpose of pedestrian search is to locate pedestrians with the same identity as the target pedestrian in the scene graph. Compared with pedestrian re-identification, this task includes the pedestrian detection part, which is more in line with the needs of real life, and has a wide range of applications in security monitoring, intelligent video analysis, personnel search and rescue retrieval and other fields. Usually single-stage pedestrian search methods use a multi-task model to simultaneously solve the two subtasks of pedestrian detection and identification. [0003] The input of the multi-task network is the scene graph, and the features of pedestrians need to be intercepted from the features of the scene graph. Since the ...
