| 摘 要： | 作为唯一远程生物认证技术,步态识别一方面越来越受到人们的重视,提出了很多相应的算法,另一方面,它又面临着很多挑战,其难点之一是如何从多帧步态中有效地提取步态特征,针对此问题,并基于步态能量图(GEI)在步态特征表示上的效果,提出了一种迭代切距离原型学习算法,假定各人的步态分布在不同流形上面,首先用切距离改进步态能量图的定义,进而用迭代的方法来解一个最优解问题,从而学习出步态原型图,再通过PCA对步态原形进行特征提取,最后进行识别,证明了该方法的收敛性,实验结果表明所提出的方法取得了比GEl更好的识别率,并证明了步态流形的假设的合理性.

| Abstract: | Being the only biometry certification techniques for remote surveillance,gait recognition,on one hand,is regarded as being of important potential value,hence a lot of algorithms have been proposed,on the other hand,it has encountered a lot of challenges.Among all of the challenges gait recognition encountered,one of them is how to extract features efficiently from a sequence of gait frames.To solve this problem,and also based on the fact that gait energy image(GEI) is effective for feature representation,an... |
