example

[0110] In order to prove that the pedestrian re-identification method based on reinforcement learning and adaptive segmentation has advantages in both performance and adaptability, the present invention conducts verification and analysis through the following experiments:

[0111] A. Experimental data set

[0112] Dataset 1: Market-1501. The data set is collected at the entrance of a supermarket on the campus of Tsinghua University. It contains a total of 1501 pedestrians with different identities. The shooting equipment is 6 cameras with different angles of view. Model) to generate detection boxes and crop pedestrian targets. In this data set, 12936 pedestrian pictures and 750 identities are divided into the training set, and another 19732 pedestrian pictures and 751 identities are divided into the test set. In addition, there are 3368 pedestrian pictures as the retrieval set, which have the same identity as the test set pictures.

[0113] Dataset 2: DukeMTMC-ReID. This d...

Abstract

The invention belongs to the field of computer vision and pattern recognition, in particular to a pedestrian re-recognition method based on reinforcement learning adaptive partitioning. The inventionintroduces a reinforcement learning method to train an intelligent network, so that the intelligent network can be driven by the data itself, and adaptively decides a partition strategy (the number ofpartitions and the size of partitions) according to the characteristics of the retrieval pedestrian. Experiments show that the invention not only improves the flexibility and generalization ability of the model, but also has a considerable application prospect.

Description

technical field [0001] The invention belongs to the field of computer vision and pattern recognition, and in particular relates to a pedestrian re-identification method based on reinforcement learning adaptive block. Background technique [0002] Against this background, the cameras in the security monitoring system are continuously collecting massive amounts of video image data every day. Often, a single camera has a limited range of monitoring capabilities, and when investigating various cases, it is necessary to search and track across multiple cameras. When a case occurs, it takes a lot of time and manpower to analyze the monitoring data only with police manpower, and it is more likely to miss the best time to solve the case. [0003] Person Re-identification (Re-ID) is an important research direction in computer vision and pattern recognition. The purpose of pedestrian re-identification is to retrieve pedestrian targets that have appeared under different cameras at dif...
