一种改进的人脸图像眼睛快速定位方法

Improved fast method for eyes location on human face image

基于广义对称变换的原理,对传统的眼睛检测算法进行了改进。首先,利用面部眉眼区域的灰度呈纵向明显变化的特点,应用积分图法快速地初步定位眉眼区域,在这些候选的区域内用对称变换法检测候选的眼睛点,最后根据先验知识确定眼睛对。实验结果表明本方法简便易行,速度快,定位准确度较高。

Based on generalized symmetry transform principle, an improved algorithm for eyes location was proposed： First, according to the characteristics of gray sharp changes on vertical, the candidate eyebrow and eye regions were selected rapidly by using integral image technique; then, a symmetry transform algorithm was applied to search eyes; finally, eyes were determined based on prior knowledge. Experimental results prove that the method is simple and easy to be realized, and higher accuracy and speed performance can be obtained.
