FIASCO: Fractal Image And Sequence COdec
Description
FIASCO is a fractal still image and video compression system for low bit-rates. I developed FIASCO during my diploma and Ph.D. thesis. FIASCO is based on the theory of Weighted Finite Automata, indroduced by Karel Culik and Jarkko Kari several years ago. The lastest compression results show that WFA low bit-rate image compression clearly outperforms the JPEG image compression standard and is on a par with wavelet codecs like Set Partitioning in Hierarchical Trees by Amir Said and William A. Pearlman.
News
4/2/2001: Due to copyright conflicts, I removed all sources and binaries from this site. The sources are not under the GPL anymore. However, all important algorithms are described in my thesis. Feel free to reuse these details to develop an open source implementation of FIASCO.
