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.
