This solution explains the reason for the error message. In short, you are trying to execute something which shouldn't be allowed.

Check your code again:
Coef = blkproc(ImageSub, [8,8], 'dct2(OriginalImage)');
The provided function is a string, but blkproc expects a function handle. How could Matlab know, what "OriginalImage" is?
Please post the relevant part of the code to allow a more explicit help.

@Pooja: Even knowing the general purpose doe not allow to suggest a specific function.
Please open a new thread for a new question. Add the concerned code there and post a copy of the complete error message.
