摘要： 步态识别是一种新的生物识别技术，它通过人行走的姿势来实现对人身份的鉴别。提出了一种新的基于人体轮廓宽度特征的步态识别方法，将视频序列中检测出的步态轮廓提取三种宽度特征并计算步态序列中宽度的变化特征，从而构成描述步态序列的特征向量。实验表明提出的方法具有较好的识别性能，是一种有效的步态识别方法。

Abstract: Gait recognition，a new biometrics recognition technology，can discriminate individuals by the way they walk.A novel gait recognition method based on the silhouette width features is proposed in this paper.Firstly，three kinds of silhouette width features are extracted from the detected gait silhouette in video sequence.Secondly，the presented approach computes the changing width features in the gait sequence.Finally，experimental results show that this approach is valid and has encouraging recognition performance.
Key words: gait recognition, background subtraction, feature extraction, silhouette width
