| 摘 要： | 提出一种基于以二次二值化图像为研究对象, 二次垂直投影为定位手段的眼睛定位方法. 先用小波8层分解原图像, 垂直和水平投影定出眼部区域的坐标; 再对原图像进行奇异值分解, 取最大奇异值的1/3.5为新值, 对图形进行重建得到对眼仁有较好刻画的准二值图. 用已知的眼部坐标在无噪声准黑白图上截取眼睛部分后, 再次用垂直投影方法得到眼仁的准确位置.

| Abstract: | A human eye localization method is described in this paper.It's based on twice binary images and twice vertical projection.Firstly,the original image is decomposed with 8-level of wavelet,and then the main area for eyes is gotten by vertical and horizontal projection.Secondly,the given image is decomposed with SVD again and a max singular value of 1/3.5 is set to be a new threshold and to reconstruct the original image for obtaining the quasi binary image which embodies eyes better.At last,eyes area is inte... |
