All the existing image steganography methods use manually crafted features to hide binary payloads into cover images. This leads to small payload capacity and   Steganography is the practice of concealing a message within another message or a physical object. In computing/electronic contexts, a computer file, message, image, or video is advantage of the degrees of freedom in stating the puzzl If we encode this as an image and open it in an image viewer, we'll see the three pixel image, but if we read this data with Python, it is simply a list of tuples, each  Test decoding ?
