File Information
Description

This program gets an image and the desidered number of partitions and fits the image histogram using a mixture of gaussian distributions and provides a clasified image
(mask).

sir
after executing this it is declaring that k is undefined

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.

Hi, could you please explain how I can use "mask" to see result of segmentation??

Greetings Prof., Very nice .. could you please let me know what exactly does the mask variable store ? As what i see it classifies each pixel that falls within each class . Am i correct in that assumption?

Thanks
