  • Bijective BWT (6 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 (113 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    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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.

JPEG2000 Shows Up Camera Gear (finally!)

Posted by Mark Nelson on 13th September 2005 | Permanent Link

JPEG2000 seems like a natural for consumer cameras, but so far, it has yet to make even a tiny step into this market. Storage capacities seem to be growing fast enough for everyone to be happy with good old JPEG as an image format.

However, Thomson announced that they are going to be using JPEG2000 chips from Analog Devices, Inc. to encode video streams in a professional camcorder.

This might sound kind of goofy - why use a still image compression format to encode video? But Thomson feels that broadcasters are going to appreciate the fact that they can directly edit the video straight out of the camera. A conventional MPEG stream has to be transcoded before editing, resulting in some loss of fidelity. No such problem with a stream of JPEG2000 images.

I don’t think anyone should see this as any sort of victory for the format. It’s precisely this kind of niche use that usually means a technology should be worried about permanent relegation to a backwater. If this is the only place that we justify the use of JPEG2000, something is awry.

    Major libraries and archives are taking up JPEG 2000, some very intensively.

    The Library of Congress will be delivering JPEG 2000 images in its National Digital Newspaper Program funded by the National Endowment for the Humanities.

    There is even a community-oriented website set up to foster adoption of the image file format.

    The website grew out of a U. Connecticut conference on the issue last Fall.
