Based on the idea that lower-limb angles of motion body contained rich information of human identification, a gait recognition method based on lower-limb angles was proposed in the paper. For each gait sequence, according to the knowledge in body anatomy, the coordinates of lower-limb joints were obtained. Then got four different angles of lower limbs. With analysis of gait cycle, the trajectories of lower-limb angles in one cycle were extracted as feature vectors. Support Vector Machine （SVM） which has an effective classify ability for small...
