i'm still new in fuzzy & image processing

i need a simple walkthrough matlab program that illustrate how can i do an image segmentation for a B & W image according to its gray level or any feature in the image, texture, frequency, luminance ....
applying the FCM algorithm.
how can i find the arbitrary initial membership matrix, and update the matrix & then show the final segmented image.

Here's your gray level thresholding example:

Yes, i saw your file & downloaded it before i see your comment here & i have to say its very well commented for I can find the answer for my questions in ur matlab file comment before I think about it :)

but what i wanted more specifically is how can i kick start this image segmentation using the FCM algorithm, what to consider regarding my image array and how can i be sure i've well segmented my image.

-To kick start I would recommend either reading papers on what you want to do, or if you're past that open a new txt file save it and begin coding.
-It's your project, figure out what you need to consider: make a decision tree (on paper or white board etc) with all of the different things you're going to have to check, what order to check them in, and how they link together.
-To make sure your image is well segmented, come up with some sample images and see how your code handles them. Are the results you expect returned? If not, what did you want instead, and where did your code fail.

Post here about the last step. I.e. here's the original picture, here's the code, this is what I expected, why isn't it working?

i need help regarding Fcm segmentation based on feature extraction of an image.
i have extracted features from an image .
i dont know, how to apply extracted features as input to FCM

i get this error:
Error using ==> ==
Array dimensions must match for binary array op.
Error in ==> fuzzycmeans at 32
distance=IMM-c;
sir send me reply to this mail address mohammadgousal@gmail.com.thanking you sir......
