Fractal Volume Compression

IEEE Transactions on Visualization and Computer Graphics 2(4), 1996, pp. 313-322.

This research is the first application of fractal compression to volumetric data. The various components of the fractal image compression method extend simply and directly to the volumetric case. However, the additional dimension increases the already high time complexity of the fractal technique, requiring the application of sophisticated volumetric block classification and search schemes to operate at a feasible rate. Numerous experiments over the many parameters of fractal volume compression show it to perform competitively against other volume compression methods, surpassing vector quantization and approaching the discrete cosine transform.
