Computer implemented color space coding that defines color space with fractal geometry

A color encoder comprising an input interface, a data repository and an output interface,

• the data repository encoding data defining a fractal shape having a plurality of iterations and a color space represented by the iterations of the fractal shape whereby colors in the color space correspond to positions on the fractal shape, the fractal shape having a fractal coordinate system with fractal coordinates for specifying the positions on the fractal shape with respect to each iteration of the iterations of the fractal shape,
• the color encoder being configured to receive color measurement data representing a color at the input interface, determine a position on the fractal shape in an iteration of the iterations of the fractal shape at which the color is present in the color space, and output via the output interface a variable length data packet identifying the iteration and the position on the fractal shape within the iteration using the fractal coordinates of the fractal coordinate system.

A color decoder comprising an input interface, a data repository and an output interface,

• the data repository encoding data defining a fractal shape having a plurality of iterations and a color space represented by the iterations of the fractal shape whereby colors in the color space correspond to positions on the fractal shape, the fractal shape having a fractal coordinate system with fractal coordinates for specifying the positions on the fractal shape with respect to each iteration of the iterations of the fractal shape,
• the color decoder being configured to receive fractal encoded color data identifying an iteration and a position on the fractal shape within the iteration, iterate through the fractal shape until the iteration and the position within the iteration are reached, determine a color of the colors in the color space corresponding to the reached iteration and the position on the fractal shape within the iteration, and output fractal coordinates of the fractal coordinate system identifying the color via the output interface.
