Abstract: Analyzing human gait has found considerable interest in recent computer vision research.So far，contributions to this topic exclusively dealt with the tasks of person identification or activity recognition.A simple but effective approach to abnormal gait analysis is proposed using computer vision techniques.After segmented the foreground object，the authors extract the feature vector reflecting the abnormal gait from the aspect ratio and achieve the abnormal gait recognition by Support Vector Machines（SVM）.Experimental results show its promising performance.
