+# `frave`
+![fractals](img/fractals.gif)
+
+`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
+> TBD!
