- Abstract:
-
Existing gait recognition methods can extract rich gait information in the spatial dimension. However, they often overlook fine-grained temporal features within local regions and temporal contextual information across different sub-regions. Considering that gait recognition is a fine-grained recognition problem, and each individual’s gait carries unique temporal context information, we propose a gait recognition method that combines local multiscale and global contextual temporal features. The entire gait sequence is divided into multiple time resolutions and fine-grained temporal features within local sub-sequences are extracted. Transformer is used to extract temporal context information among different subsequences, and the global features are formed by integrating all subsequences based on the contextual information. We have conducted extensive experiments on two public datasets. The proposed model achieves rank-1 accuracies of 98.0%, 95.4%, and 87.0% on three walking conditions of the CASIA-B dataset. On the OU-MVLP dataset, the model achieves a rank-1 accuracy of 90.7%. The method proposed in this paper has achieved state-of-the-art results and can provide reference for other gait recognition methods.
