Hi, I want to convert an image into a string of 0's and 1's using huffman transform and hide it in another image. Can anyone help what method I can use so that I can re-extract the hidden image with Huffman transform image?

A simple way is using a conversion from RGB to grayscale using rgb2gray(). Then proceed with builtin fcns: hist, huffmandict, huffmanenco.
