Abstract When the gait database contains the only gait feature, the larger the number of individuals is, the longer time the recognition algorithm costs and the lower the recognition ratio is. Aiming at this problem, a structured gait feature expression and fast gait recognition method is presented. The structured gait feature are made up of gait information, individual height, sex, age and other information. These feature components are sampled by different sensors and used independently. The proposed gait recognition algorithm utilizes the structured feature to deal with the gait recognition hierarchically. The large identification range is narrowed. The experimental results demonstrate that the proposed method improves the recognition speed and gains higher identification precision.
