【摘要】 在局部二值化基础上采用了基于灰度比对、对称相似度测量和方差投影相结合的方法进行人脸预处理,改进了对称相似度测量的具体实现方法,并与几何归一化交叉进行。改进后的方法在保证速度的前提下增强了系统的适用范围,特别是对大角度倾斜的人脸预处理更具优势。更多还原

【Abstract】 In this method,grayscale comparing and comparability detecting combine with the variance projection function eye location method,and do local binary first.Improve the comparability detecting method crossing with the geometry normalized.Experiment re-sult show that we reduce consuming time and expand the adaptive range especially for the large rotation image.更多还原
