Problems solved by technology

This method works well and has good robustness, but requires a large number of labeled samples and a large system overhead
When marking samples, it is difficult to find samples that are similar or dissimilar as a whole. Absolute similarity and dissimilarity also limit the marking of most samples. The samples with different degrees of similarity are treated uniformly, and the role of marking is not maximized.

Embodiment Construction

[0052] The pedestrian re-identification method based on self-procedural feedback provided by the present invention is aimed at the significant difference between the pedestrian image in the video surveillance scene and various images in other situations, and is based on the structural characteristics of various parts of the body in the walking state. , divide it into several fixed component areas, use the area as the basic processing unit, and calculate the uncertainty of the samples, mark the samples with relatively large uncertainties, and finally reorder according to the optimized score size to realize the self-based The whole process of the pedestrian re-identification method with step feedback. specific implementation

[0053] Computer software technology can be used to support process operation. see figure 1 , the flow process of the embodiment includes steps as follows:

[0054] Step 1. Divide all the samples to be queried, calculate the intimacy between the samples ...

Abstract

The invention provides a pedestrian re-recognition method and system based on self paced feedback. The method comprises the steps that sample areas are divided, and the sample intimacy is calculated;a query sample is input to calculate the score and uncertainty of each sample to acquire a query matching result; at the same time, the quantitative evaluation is carried out on the ranking difficultyof each sample; samples difficult for ranking are selected to form a sample set to be fed back, and a user mark is submitted; after user feedback is completed, a sample mark is updated by the feedback sample set; the ranking score and the difficulty of each sample are recalculated until the final desired search goal of the user is found. According to the feedback technology based on self paced learning and active learning, the information amount of an unlabeled image is fully used; the sample the most difficult for ranking is selected and provided for the user mark; user marks are effectivelyreduced; and the right goal can be accurately and rapidly found.

Description

technical field [0001] The invention relates to the pedestrian re-identification problem in the field of video investigation, and belongs to a pedestrian re-identification method and system based on self-procedural feedback. Background technique [0002] Pedestrian re-identification in surveillance video is a technique for matching specific pedestrian objects in a multi-camera environment with non-overlapping illuminated areas. In the actual video investigation, investigators mainly use the moving pictures and trajectories of the same pedestrian object to quickly lock, check and track the suspected target. The traditional video investigation mode of manual browsing requires a lot of manpower and time, and it is easy to delay the time to solve the case. Pedestrian re-identification technology facilitates video investigators to quickly and accurately discover the moving pictures and trajectories of suspected targets, which is of great significance to the public security depar...
