intrec(Z)

function intrec(Z)
%INTREC Performs morphological character recognition
%INTREC(X) recognizes the characters (in integer form) present in the
%image X and displays it as output. INTREC uses morphological operations(like
%Dilation and Hit-or-Miss transform) to recognize characters.The charecter
%size of the integers present in the image should be exactly 26, otherwise 
%it may not recognize it.
%
%Example:
%X=imread('testimage1.bmp');
%imshow(X)
%intrec(X)
%The digits found in the image are:
%0
%3
%5
