Abstract

The pedestrian re-identification system comprises a multi-stream feature distance fusion system used for calculating the image similarity between an image p to be detected and each reference image inan initial reference image set G, a sorting system used for sorting the reference images according to the image similarity, and a re-sorting system based on k neighborhood distribution scores. And thereordering system is used for reordering the reference images in the initial ordering list according to the k neighborhood distribution score on the basis of the initial ordering list. The inventionfurther discloses a pedestrian re-identification method, and the pedestrian re-identification system is adopted by the pedestrian re-identification method. The pedestrian re-identification method aimsat two main factors influencing pedestrian re-identification, namely image similarity calculation and image sorting, improvement is carried out respectively, and compared with the prior art, the improvement of any one aspect can improve the accuracy of pedestrian re-identification. And an optimal pedestrian re-identification effect can be obtained through the combination of the improvement of thetwo aspects.

Description

technical field

[0001] The invention relates to the field of image recognition, in particular to a pedestrian re-identification system for retrieving a specific pedestrian in an image, and also relates to a pedestrian re-identification method. Background technique

[0002] Person re-identification aims to retrieve the same person from a reference image set with different camera views. Pedestrian re-identification is an important and challenging topic in video surveillance and public safety. The current pedestrian re-identification is generally retrieved from the reference image data set by the image similarity between the image to be tested and the reference image, and then based on the similarity Then the reference image with the highest similarity with the image to be tested is taken as top-1.

[0003] For the similarity calculation part of pedestrian re-identification, due to the change of camera angle and human body posture, pedestrian re-identification mainly faces the...
