A multi-part guided foreground enhancement method for person re-identification was proposed in order to solve the problem that the performance of person re-identification model was overly depend on background environmental factors. The model’s attention to the person’s foreground was enhanced by employing mask-guided enhancement and self-enhancement strategies, while retaining some background information. This effectively reduced the model’s dependence on background information and improved its generalization ability. A bottleneck optimization module was integrated into the backbone network, utilizing dilated convolutions to enlarge the model’s receptive field while maintaining the original parameter scale, thereby improving the overall performance of the model. The experimental results demonstrated that the proposed model achieved Rank-1 accuracies of 95% and 88.3% on the Market1501 and DukeMTMC_reID datasets, respectively. The effectiveness of the multi-part guided foreground enhancement method was verified, which strengthened the foreground while incorporating appropriate background information, and significantly enhanced the performance of the baseline model.
