It contains the email address of the author of the program. If you google for that particular source, you will find the original version of it as a page under that URL, http://web.vu.union.edu/~shoemakc/watermarking/matlab/dct1_recover.m

If you are telling me that it is beyond your abilities to do a simple adaptation of code so that it works with a single color channel instead of converting the image to grayscale, then my interpretation of that would be that the course is beyond your abilities and you need to drop it. > its a part of final sem project In any mathematical or engineering or scientific field of study I can think of, inability to make a change this simple would indicate that the person is not suitable for graduation. > thats why was looking for quick reply > dont want to mess with my grades ,u guys know indian education system.... I do *not* know the Indian education system. I have formed certain _impressions_ of the Indian education system, but I have been hoping that those impressions are wrong. You expecting me to write your code for you for your final semester project, and you considering that expectation as natural and customary for your education system, tends to give further evidence to those bad impressions. It would be faster for you to make these code changes for yourself than for you to discuss the matter further. It is probably only 3 or 4 lines of changes.
