Abstract

The aim of this research was to determine which channel in rgb color space is the most suitable (regarding perceptibility) for a pixel manipulation in a spatial domain data hiding techniques. 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).
