Gait‐D: Skeleton‐based gait feature decomposition for gait recognition

Abstract

The general silhouette-based gait recognition methods usually rely on binary human silhouette, which is easily affected by external factors, making it unsuitable for situations while wearing heavy clothes or carrying objects, etc. In this study, a new skeleton-based gait recognition model is proposed. The model first extracts the spatial and temporal features of gait using the space and time relationship between body joints, and second, it eliminates redundant features by decomposing the feature map, to achieve a better recognition accuracy in the presence of external factors. Through abundant experiments on two common datasets, CASIA-B and OUMVLP-Pose, the proposed model has been proved to have higher recognition accuracy and remarkable robustness.
