How to segment 2D breast images using fuzzy c-means algorithm

I am new to the Matlab. I am basically from maths background. I already read CT image in .IMG format. I need the code how to segment the 2D breast image using fuzzy c-means algorithm. Also, how to find average pixel value only in the image region. Please help me in this occasion, it would be more helpful for my further process.

How to upload my .img file format. I tried to upload the file but I cann't. Please give me any other way to upload the .img file.

After you have read the data into matlab, imwrite() it to a jpeg or tiff file, and upload that image file.

I am guessing you are using a DICOM file since this is a CT image? If so, use

   Image = dicomread(filename);
