Need help after cropping the face what is the next move to crop the eye region? any method can do it? i tried some algo not working maybe i missed something.. ty for help =)
this is the input image <http://i648.photobucket.com/albums/uu201/myjonas13/46_zps2e1b0ca2.jpg> this is the result i used to crop the region of the face <http://i648.photobucket.com/albums/uu201/myjonas13/resultss_zpsf429db89.jpg>
now this is the code I used..
%%%%%Reading of a RGB image
wa = imread('46.jpg');
G = wa;
I=rgb2gray(G);
BW=im2bw(I);
% minimisation of background portion
[n1 n2]=size(BW);
r=floor(n1/10);
c=floor(n2/10);
x1=1;x2=r;
s=r*c;
for i=1:10
y1=1;y2=c;
for j=1:10
if (y2<=c | y2>=9*c) | (x1==1 | x2==r*10)
loc=find(BW(x1:x2, y1:y2)==0);
[o p]=size(loc);
pr=o*100/s;
if pr<=100
BW(x1:x2, y1:y2)=0;
r1=x1;r2=x2;s1=y1;s2=y2;
pr1=0;
end
end
y1=y1+c;
y2=y2+c;
end
x1=x1+r;
x2=x2+r;
end
%TRACE THE FACE
L = bwlabel(BW,8);
BB = regionprops(L, 'BoundingBox');
BB1=struct2cell(BB);
BB2=cell2mat(BB1);
[s1 s2]=size(BB2);
mx=0;
for k=3:4:s2-1
p=BB2(1,k)*BB2(1,k+1);
if p>mx & (BB2(1,k)/BB2(1,k+1))<1.8
mx=p;
j=k;
end
end
%figure,imshow(I);
%hold on;
%rectangle('Position',[BB2(1,j-2),BB2(1,j-1),BB2(1,j),BB2(1,j+1)],'EdgeColor','r' )
%CROP THE INTEREST IMAGE
I2 = imcrop(G,[BB2(1,j-2),BB2(1,j-1),BB2(1,j),BB2(1,j+1)]);
imshow(I2)
