In order to address the problem that the detailed features of pedestrians are not prominent and the pedestrian pictures are obscured in unique environments in the process of person re-recognition, we propose a person re-recognition method with a multi-grain size generative adversarial network. Firstly, we use the generative adversarial network to recover the occluded pedestrian pictures; secondly, we improve the traditional multi-granularity network by adding an Efficient Channel Attention for Deep Convolutional Neural Networks (ECA-Net) on the coarse-grained branch to focus on the feature information in the pedestrian pictures and use the High-Resolution Net (HRNet) for pose estimation on the fine-grained branch to divide the pedestrian pictures into nine parts, to enhance the network’s learning of more detailed features of pedestrians, and thus improve the accuracy of pedestrian re-recognition learning, which in turn improves the accuracy of person re-identification.
