You did not provide the original image and you did not provide the error messages.

error is

Error using .* Matrix dimensions must agree.

Error in Untitled2 (line 41)

ccc1=sum(sum(u1.*u1.*IM))/sum(sum(u1.*u1));

[sam CP]

i solved this error by adding imresize in line 41. Then my input and output image is diplayed as blank ..

I want to process this code on the attached image too.

The indentation is all messed up, and all the wonderful comments that I'm sure you added to the code somehow got stripped away upon posting. So all I can suggest is to replace this:

imshow(uint8(IMMM));

with this:

imshow(IMMM, []);
drawnow;

when i use the above code in my program , then my input image is displayed and then i got error .

Error using .* Integers can only be combined with integers of the same class, or scalar doubles.

Error in Untitled2 (line 47) ccc1=sum(sum(u1.*u1.*IM))/sum(sum(u1.*u1));

Try casting everything to double.

Yes.. Hence this program run without showing error., but i got the result as blank image.
