The inaccurate location due to the high similarity between the eyes and brows is avoided by changing the eye template to eye-brow template.

将眼睛模板转化成眼眉模板后,避免了由于眉毛和部分眼睛相似造成的特征点错误定位。

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 regionswere 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.

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。

The expression of eyesis one of the most important parts in body language.

眉眼语是人体语言的重要组成部分。
