The design of a Hilbert fractal codec, a key-component for ROC of color images, is discussed. The implementation efciency of the codec is critical since it determines the feasibility of the global compression scheme. We discuss the role of the Hilbert fractal codec in the global codec scheme and the high-level design methodology that leads to a successful implementation of the codec design.
