A Simple Method for Embedding and Restoring Images

A method has been proposed for generating image A' by embedding another photographic image (image B) in a photographic image (image A) and restoring image (image B') by extracting information from image A'. In this paper, we improve the conventional method and propose a simple method that can make the change from image A to image A' smaller than the conventional method. Our method generates image A' using each digit of pixel values of image B, which consists of the three digits. To verify the effectiveness of our method, we conducted experiments using various images. As a result of the experiments, our method improved the pixel change rate between image A and image A' without almost degrading the pixel change rate between image B and image B' compared to the conventional method.
