摘要
在对传统积分投影法实现人脸标准化算法及其特点进行分析的基础上,针对其速度较慢的缺陷,利用小波变换的多分辨分析特性,提出了基于小波分解和积分投影的人脸标准化算法.采用ORL人脸数据库进行仿真实验.结果表明:该算法在保持原来积分投影算法优点的同时,标准化速度可以提高将近4倍,具有一定的实用价值.
In this paper, an improved face image standardization method based on wavelet decomposition and integral projection is presented by using Multi-Resolution Analysis（MRA） of wavelet transform,aimed at improving speed of traditional face image standardized method --integral projection method.Experimental results based on ORL face database demonstrate that the method can improve the processing speed almost 4 times at speed, besides with the advantages of integral projection method, and has great merit in face recognition.
