Fraktal Image Compression under Windows

Dr. Andreas Kassler, Researcher at the University of Ulm in Germany.

fracomp is a program for compressing images using the fractal transfrom and has additionally features for image processing.

Fracomp can import and export several image formats like TIFF, GIF, JPEG, BMP, and can filter (high- amd lowpass), reduce colors and and and. Please read the Online-Help for further information. fracomp uses for fractal image compression algorithms partly developed by Y. Fisher (see DISCLAIM.TXT). To process color images, several add-ins were developed Main features are:

new file format
no need for command line parameters
supports compression of True-Color images using RGB- or YUV- color space
compression factors up to 100:1 and more
at high compression better image qualitiy than JPEG
typical compressionrates of 50:1 at a PSNR of about 30 dB.
coding of a 600 x 400 pixel image in less than 10 s
Decoding is done by iterative decoder or pyramid decoder (very fast)
zoom in only by manipulating the fractal code
select only parts of an image an zoom in is possible
supports Drag- and Drop for all implemented file formats

Samples of fractal codes:
COLLIE.QIF, HUMB_YUV.QIF, FLORIAN1.QIF, BILD.QIF, FLO_YUV2.QIF, TINA1YUV.QIF

Sample images:
COLLIE.BMP, HUMBIRD.BMP, TINA.BMP, FLORIAN.BMP

To install this program first expand Source1.zip into a directory called Disk1, then expand Source2.zip into a directory called Disk2. The run Setup.exe from the Disk1 directory.

To use this program you probably need a knowledge of German, or at least a German dictionary; I included it despite this because there is so little available software for fractals.
