Optimum parameters for hybrid fractal image coding

Abstract

We evaluate the fidelity/compression performance of fractal transforms over a range of parameters, using an rms error metric. We consider order of approximation, different (fixed) block sizes and various degrees of image searching. We find that higher orders of the Bath Fractal Transform (BFT) are a better means of gaining accuracy at a given bit rate than… (More)
