Hi,
I have made a function for thresholding. When i compare result of my function with the graythresh function of MATLAB for gray scale images, it is almost same. But when i execute my function for dicom images than it gives different results as from graythresh function of MATLAB. I just want to know that how can i fix my problem?

I suspect this has something to do with datatypes (dicom images can be uin16, while grascale images in general are uint8). You can always 'edit graythresh' to see the code and compare against what your function does. Not enough information in the question to say more.
