This is not a MATLAB question, and should have been researched in a different forum. MATLAB Answers is about the MATLAB language and libraries, not about theory or algorithms. You should have done research, not re-opened the question.
The answer to your question is that any set of data that can be represented on a computer is ultimately represented as a sequence of bits. The "text" gets transformed to a sequence of bits and the bits are hidden in steganography. RGB images can be transformed into sequence of bits:
temp = dec2bin(YourRGBImage,8)-'0';
bitvector = reshape(temp.',[],1);

Yes that only I meant,that is if an digital image can be hidden inside cover image using PVD. And I know that PVD is an steganography method so it is sure that the color image that I mentioned in the question was mentioning an digital image and not as an object.After checking many papers I thought PVD can only be used to hide binary values so to clear that doubt I just asked the question.

Anything that can be expressed in finite binary can be hidden, provided the cover image is large enough. The hiding algorithms do not care what the bits mean.
