I suggest you look for an algorithm here http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems then code it up into MATLAB.

23.3.8 Image Hiding, Data Hiding, Steganography, Steganalysis

      23.3.8.1 Data Hiding, Steganography, LSB, Least Significant Bit
      23.3.8.2 Halftone Images, Compressed Images: Image Hiding, Data Hiding, Steganography
      23.3.8.3 Surveys, Image Hiding, Data Hiding, Steganography

I have an LSB watermarking demo that I've posted before. You can search for it or just ask and I'll post it again here.

i'm not ask about that. my program is complete. i want to call variable A in hiding pushbutton and process them into extract pushbutton. just about GUI, graphic user interface.
