frave

frave is an image compression algorithm based on complex-base system fractals.

Decomposition of an image

Unlike other compression algorithms frave works on tame-twindragon fractals rather than on blocks.

Compression pipeline

• Decomposing image to fractals using complex-base numeral systems
• Saving the residues of each block
• Quantization based on dividing the smallest layer of fractals
• Entropy coding with ANS

Compression rates
