hey guys, let me know what you think of the code, if there is anything you like about it or improvements that can be made to it. Thanks

04 Dec 2012 EM image segmentation Apllication of EM algorithm to segment a grey scale image on diferent classes Author: Jose Vicente Manjon-Herrera

Some people want to know how to view the segmented image. For example suppose you have two classes ie k=2; us the following code to view it
[row col] = size(ima);
final_img = zeros(row,col);
for i=1:row
for j=1:col
if mask(i,j)==1
final_img(i,j)=1;
else
final_img(i,j)=255;
end
end
end
imshow(final_img/255);
This is a naive way of viewing it .. you may have to change somethings if k>2. Anywayz hope it helps. The mask basically stores the segmented image.
