摘要
利用图像灰度分布的特性,从计算对称值的角度出发,利用梯度对称变换,实现了一种自动定位人脸图像中眼睛的算法。经计算机模拟实验表明,它对一定程度的背景干扰以及光照的变化不敏感,对正面人脸且在眼睛张开的情况下,对称变换的定位准确率可以达到95%以上。
A facial features location algorithm automatically to locate eyes is introduced. Using gamma distribution and gradient symmetry transform, the core of this algorithm is to compute each pixel's symmetry values. The simulation experiment by computer demonstrates that this algorithm is not sensitive to the background interference and irradiant metamorphose in certain lever. Under a circumstance of a facial face and open eyes, the accuracy of allocation of symmetry transform can reach 95% or more.
