利用matlab实现人脸和人眼的识别算法

function [face_a,skin_region]=face(I); skin_region=skin(I); se = strel('disk',5); se2 = strel('disk',3); er = imerode(skin_region,se2); cl = imclose(er,se); dil = imdilate(cl,se); % morphologic dilation dil = imdilate(dil,se); cl2 = imclose(dil,se); d2 = imfill(cl2, 'holes'); % morphologic fill facearea = bwdist(~d2); % computing minimal euclidean distance to non-white pixel % figure;imshow(facearea,[]); % imshow(d2); face(:,:,1)=double(I(:,:,1)).*d2; face(:,:,2)=double(I(:,:,2)).*d2; face(:,:,3)=double(I(:,:,3)).*d2; face_a=uint8(face);
