Attribute-guided Feature Extraction and Augmentation Robust Learning for Vehicle Re-identification
This work addresses vehicle re-identification for intelligent transportation systems, presenting an incremental improvement with specific gains in accuracy.
The paper tackles vehicle re-identification by proposing a multi-guided learning approach that uses attribute information and novel random augmentations to improve robustness, achieving a mAP of 66.83% and rank-1 accuracy of 76.05% in the CVPR 2020 AI City Challenge.
Vehicle re-identification is one of the core technologies of intelligent transportation systems and smart cities, but large intra-class diversity and inter-class similarity poses great challenges for existing method. In this paper, we propose a multi-guided learning approach which utilizing the information of attributes and meanwhile introducing two novel random augments to improve the robustness during training. What's more, we propose an attribute constraint method and group re-ranking strategy to refine matching results. Our method achieves mAP of 66.83% and rank-1 accuracy 76.05% in the CVPR 2020 AI City Challenge.
