Try using imclose() to join small gaps. Then take the largest blob. If the neck is separated from the face, the face will be larger and you will extract only the face. bwconvhull() may also be of interest to you. See my attached demo for taking the N largest or smallest blobs.

OK, let's end this thread . I don't want to keep answering the same thing in two different threads.
