Data hiding based on generalised exploiting modification direction method

Abstract

Two schemes using the exploiting modification direction (EMD) method to obtain good stego image quality and increase embedding capacity were respectfully introduced by Zhang and Wang and Lee et al. This study proposes a data-hiding scheme based on an improved EMD method. According to experimental results, the proposed scheme retains high embedding capacity and good stego image quality.
