Abstract

Due to the complexity of the person re-identification scene, it is easy to be affected by visual changes such as illumination, occlusion, posture, etc, which makes the extracted person features will be insufficient and feature discrimination is poor, which in turn will lead to low retrieval accuracy. To address the above problems, a multi-scale attention pyramid network (SOAPNet) based on non-local block guidance of the spectral is proposed. First, the atlas non-local blocks are introduced into ResNet50 to capture remote dependencies more robustly and flexibly, so as to realize a wider range of information perception in the feature extraction stage; then, the multi-scale attention pyramid network is introduced into ResNet50, so that the model can focus more on the most critical and discriminative information in the person images, and this multi-scale attention strategy effectively solves the problem of The problem of insufficient features and poor discrimination in the person re-identification task, which enables the model to better distinguish person with different identities and extract more robust features. Experiments on Market1501, MSMT17, and DukeReID show that Rank1 is improved by 0.7%, 0.9%, and 1.2%, respectively, and mAP is improved by 0.5%, 1.0%, and 1.4%, respectively. The proposed method can significantly solve the above problems.
