摘要:

本文提出了一种简单实用的步态识别算法.该算法使用背景减除的方法检测人的运动区域;然后统计运动区域上像素的角度直方图,提取角度直方图向量作为步态特征;以欧氏距离作为度量,使用标准模式分类器用于步态识别.实验结果表明,本文提出的算法识别性能较高,并具有计算代价小等优点.

关键词: 生物特征识别 步态识别 背景减除 角度直方图

Abstract:

This paper proposes a simple but efficient algorithm of gait recognition. In each image sequence, background subtraction and related processes are car  ried out to segment and track the moving silhouettes of a walking figure from the background. By computing the angles of the pixels in the moving silhou ettes, we can get the angle histogram vectors as the gait signature. Supervised pattern classifiers with Euclidian Measurement are finally performed for recognition. Extensive experinacnts using the NLPR database demonstrate that the proposed algorithm has a high recognition performance with low computa tional cost.
