Color Processing - A New Approach Based On Discrete Dynamic Systems

Nowadays, although an increased number of people tend to use high-quality images for their daily activities, there are some applications where it is useful to have a reduced number of colors in our images. In this article, a color reduction approach is presented based on Cellular Automata (CA). More specifically, we exploit the inherent properties of CA, in order to locally detect the dominant color values and replace the colors of a predetermined neighborhood with these values. This method is applicable to any type of color image and it can accommodate any type of color space. The final results indicate that there is enough space for future improvements in this field.
