First, get rid of the text, if it's in the image. Then threshold the image to binarize it. Then label the image with bwlabel(). Then use ismember to get rid of blob #1 and keep all other blobs. This assumes that there is no strand of brightness that connects the skull to anything inside that you want to keep. So, it's like 2 or 3 lines of code. See if you can do it yourself first, but let us know if you can't.

Muhammad,
I use a program known as AFNI for such skull stripping. AFNI has been developed by the National Institute of Health (NIH) AFNI can be found here for download (it's free- http://afni.nimh.nih.gov/afni)
and the part used for skull stripping is called 3dSkullStrip http://afni.nimh.nih.gov/pub/dist/doc/program_help/3dSkullStrip.html

Muhammad, AFNI works only only a UNIX/Linux based system (Ubuntu, Debian, CentOS, MAC-OSX) You just run your nifiti images throught he 3dSkullStripper and in my experience it does an excellent job around 98% of the time. All the documentation on how to use it is available on the website in my original answer.
