Abstract

The present invention relates to the technical field of intelligent image retrieval, and more specifically, relates to a pedestrian re-identification method based on multi-view image feature decomposition. Starting from the target image classification problem, combined with a capsule network, a pedestrian image multi-view image feature generation network is constructed. , decompose any pedestrian image to obtain multi-view image features and the similarity under this view. The features of the same viewing angle are directly used for re-identification, while the features of different viewing angles must undergo feature conversion. In the present invention, the feature conversion matrix is ​​obtained by using the BP neural network, which solves the problem of measuring the features of different viewing angles. Experiments show that the decomposition of pedestrian images is of great help to improve the accuracy of pedestrian re-identification.

Description

technical field [0001] The present invention relates to the technical field of intelligent image retrieval, and more specifically, to a pedestrian re-identification method based on multi-view image feature decomposition. Background technique [0002] As social public security is getting more and more attention, a large number of surveillance cameras have been installed in many important places. The surveillance video captured by the surveillance cameras can provide the public security department with clues to detect major criminal cases such as terrorist attacks and mob fights. Pedestrian re-identification is an automatic target recognition technology that quickly locates human targets of interest in the surveillance network, and is an important step in applications such as intelligent video surveillance and human behavior analysis. The main purpose of using pedestrian re-identification technology is to solve the retrieval problem of pedestrians in the field of security moni...
