Z. Baharav, D. Malah, E. Karnin. Hierarchical interpretation of fractal image coding and its applications to fast decoding. In Intl. Conf. on Digital Signal Processing, Cyprus, July 1993.
The basics of a block oriented fractal image coder, are described. The output of the coder is an IFS (Iterated Function System) code, which describes the image as a fixed-point of a contractive transformation. A new hierarchical interpretation of the IFS code, which relates different scales of the fixed-point to the code, is presented and proved. The proof is based on finding a function of a continuous variable, from which different scales of the signal can be derived. Ist application to a fast decoding algorithm is then described, leading typically to an order of magnitude reduction of computation time.
