| 摘 要： | 提出一个新的步态识别算法.首先通过计算轮廓图距离来检测异常步态轮廓图,并利用平均近邻图与平均轮廓图重建异常的图像.然后将对象的步态能量图分解为两部分,并分别为每一部分生成一系列扩展图像,从而构造出能量分解图.接着根据主干图与步态偏移图的对应关系消除静态形状信息,并进行脚部区域校正,从而构造出运动偏移图.最后,使用能量分解图和运动偏移图共同进行分类.实验结果表明,本文算法的识别率远远高于3个典型算法.

| Abstract: | A new gait recognition algorithm is proposed.Abnormal silhouettes are detected based on silhouette distance,and averaged adjacent image and averaged silhouette are utilized to reconstruct abnormal silhouettes.The decomposed energy image consists of two series of images which are generated from each part of the decomposed gait energy image.The relation of trunk image and gait deviation image is utilized to remove static shape information,and feet area is rectified to generate motion deviation image.The decom... |
