Abstract
This paper presents a graphical comparative study of steganographic methods in the DCT domain. This graphical representation allows at-one-glance comparison among steganographic methods, showing the relative performance of each method with respect to the ideal methods for the metrics considered. Six representative DCT-based steganographic methods are selected and fairly compared in terms of six significant evaluation criteria. From the comparison results, we found some trends in recent evolution of steganographic methods and possible future development directions.
