How can I classify faces for their geographical background? My code is below, but I don't think it'll work for classification.

cartman=imread('5.jpg');
l=size(cartman);
counter = 0;
for i=1:l(1)
  for j=1:l(2)
    for k=1:3
      if (cartman(i,j,k) > 100)
        cartman(i,j,k) = 255;
        counter = counter+1;

        else
          cartman(i,j,k) = 0;
        end
      end
    end
  end
  fprintf('i:%d\nj:%d\nk:%d\ncounter:%d\n',i,j,k,counter);
  image(cartman);
  imshow(cartman);

Do you mean like you want to identify the name of the person based on where you think the background is (desert, boat, football stadium, etc.)? Please attach a sample image. Classify the face into what categories? Race, gender, what???

Classification for the geographical background. Like from which region person belongs (country, province etc).

Do you think a 20 line program can do that? Not even a human observer can do that. A few have tried to classify a face's race:
