Hi,
First i would really appreciate the hard work that you made. But this approach fails for african ethnic people. I tried to extract skin for african people with different skin values. But unfortunately it fails.

Hi,

what does this portion doing. Why for k=3:4:s2-1?

[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

Thanks in advance.
