above's are morphological operation types.Basic syntax as follows

>>morph_output = bwmorph(input_binary_img,operation) ;

operations are 'bothat', 'bridge', 'clean', 'close', 'diag', 'dilate', 'erode', 'fill', 'hbreak', 'majority', 'open', 'remove', 'shrink', 'skel', 'spur', 'thicken', 'thin', 'tophat'.

example code and output as  below.Here we use Morphological Removes interior pixels method.
