kmeans image segmentation

Thank you.

how do i get to see the code?

Works nicely.
A little word of advice, if I may...
By adding the following two lines (in lines 25-26) you will be capable of dealing non integer inputs also (matrix of double's in my case):
Consider performing rgb2gray to deal with color image inputs as well.

greyLevels=2^8-1; % Number of gray levels
ima=round(greyLevels*ima/max(ima));

Best regards, and keep the good work!

very good

where is the statement for loading image by using this code..?? :(

Excellent code, but please, I need to extract the pixels for each classes to calculating some statistical proprities, like mean or std. can you help me please !!

Can anyone help me in how to implement this function on image ??

Excellent code, but I came across a problem in this code. Whenever number of clusters specified are more than possible partitions of the image the algorithm got stuck. Here is the solution.

find following line in the given code
if(mu==oldmu) break;end;

now add following lines of code before this line.
for i=1:k,
if(isnan(mu(i)))
mu(i) = i*m/(k+1);
end
end

The problem was occuring when NaN was encountered in centroid computation.

Doesn't work for me. Tried to run it on the Shepp-Logan phantom:

>> [u,m]=kmeans(phantom(128),4);

??? Attempted to access h(1.2); index must be a positive integer or logical.

Error in ==> kmeans at 35
if(ima(i)>0) h(ima(i))=h(ima(i))+1;end;

i don't how its work with image !! do u have GUI ?

Can you pls tell me for which k=? did you obtain the result from the image?

>Mahmoud Shehadeh I'm gonna send you an email.

k..tq..does it works on the grayscale image..

'Mahmoud'..do you have the corrected code

anyone can help me..why i didn't successfully execute the results..
i'm using the jpeg image.tq

trabajo bién

nice !

Please help me how to execute this code in matlab

Dank!

it is very beauteful,excellent!

im doing my final year project in image segmentation based on MRF with ANT COLONY SYSTEM,i dont have any idea ab't that,can u help me,my first module is k-means,can u explain k-mans in depth.

good

good

please help me, how to use this code

I need a help from u to solve a paper in image processing

Good work, this code very useful for me, but I need method hierarchical clustering for image..., Any idea for me?

workes good

i m doing my final year project of mini portions segmentation method in face recognition using matlab. may i know how to put my cropped small portions of the face into matrix (eg: 6x9 matrix, where 6 refer to number of photos, n 9 refer to the number of small portions). by the way, i also would like to know how can i compare the matrix column by column in order to get the eigenvalues. n i m new to matlab, so i hope u will help me to clear my doubts. if u have to source code, pls send a copy to me. thanks and really appreciate for your help. Hope can hear from u soon.

Just Perfect. Very fast and great code.

K-means is a classic un-supervised classification algorithm. In your code, is there new ideas about k-means? And can you compare the k-means,ISODATA,SOM mathods?
