  • Bijective BWT (2 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (107 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

UNH company gets grant

Posted by Sachin Garg on 26th September 2005 | Permanent Link

Chaoticom Technologies, the research and development division of the University of New Hampshire’s first spin-out company, has received a $50,000 grant from the N.H. Industrial Research Center (NHIRC) to develop the next generation of video compression technology.

Chaoticom Technologies will match the grant with in-kind support. The Durham-based division is part of Groove Mobile, formerly known as Chaoticom and based in Andover, Mass. It is headed by UNH Math Professor Kevin Short, who discovered cupolets-the new class of nonlinear waveforms in chaotic systems which lies at the heart of the company’s compression technology.

UNH math professor Marianna Shubov, co-director of UNH’s new Center for Dynamics Research, will collaborate with Short. Besides video compression, they will also investigate new audio compression technologies.

“The signals analysis tools have applicability well beyond music and video compression, especially in homeland security applications,” said Short, co-director of the Center for Dynamics Research, in a press statement.
