clc
[filename pathname] = uigetfile({'*.jpg';'*.bmp'},'Select MRI');
inputimage=strcat(pathname, filename);
I = imread(inputimage);
figure,imshow(I), title('input');
se = strel('disk',7);
closeBW = imclose(I,se);
figure, imshow(closeBW);title('close operation');
afterOpening = imopen(closeBW,se);
figure, imshow(afterOpening,[]);title('open operation');
J=I-afterOpening;

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.
