Suitability of the RGB Channels for a Pixel Manipulation in a Spatial Domain Data Hiding Techniques

The aim of this research was to determine which channel in RGB color space is the most suitable to hide information in the spatial domain of an image. Modern data hiding techniques rarely use RGB color space. For this purpose three custom test targets were generated. The research also shows the behavior of two closely related colors in the PS (Print-Scan) process. The results are interpreted using both a quantitative method (statistical comparison) and a qualitative method (visual comparison).
