That comment is not a question; there is nothing to be done for it.

Hi, I'm writing my bachelor thesis and I tried use this code to skull removal but it doesn't work. I work on dicom files, but on .jpg it doesn't work too. Can u help me? What I do wrong?

Well it's nothing like my code. Anyway, you should threshold the image to find everything that's skull, then use that to erase the skull pixels.

skull = grayImage > someValue;
grayImage(skull) = 0;

There are a few other things you could do to make it better but that's basically it.
