WebAug 9, 2014 · OK. You need to normalize by sum(tf), not max.sum(tf) is essentially the dimensions of your image (prod(size(im);).I see why it is not (entirely) correct. You almost have it right. You just didn't normalize properly. Remember, when you sum up all of the probabilities, the total must be equal to 1.
