MIX-Net: Hybrid Attention/Diversity Network for Person Re-Identification

Person re-identification (Re-ID) networks are often affected by factors such as pose variations, changes in viewpoint, and occlusion, leading to the extraction of features that encompass a considerable amount of irrelevant information. However, most research has struggled to address the challenge of simultaneously endowing features with both attentive and diversified information. To concurrently extract attentive yet diverse pedestrian features, we amalgamated the strengths of convolutional neural network (CNN) attention and self-attention. By integrating the extracted latent features, we introduced a Hybrid Attention/Diversity Network (MIX-Net), which adeptly captures attentive but diverse information from personal images via a fusion of attention branches and attention suppression branches. Additionally, to extract latent information from secondary important regions to enrich the diversity of features, we designed a novel Discriminative Part Mask (DPM). Experimental results establish the robust competitiveness of our approach, particularly in effectively distinguishing individuals with similar attributes.
