MATLAB: Dear all, How to embed message bits in DWT coefficient values

digital image processingiwttransfer functionwaveletWavelet Toolbox

I wanted to embed some message bits in DWT coefficient values of an image and transmit. After embedding the message bits when I have performed uint8() to transmit the image as a grayscale image, at the receiving end, I am not able to get back the message bit from the same coefficient values. On the other hand, if I don't perform uint8() function, I can retrive the message bit successfully.
