    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.

    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.

IIPimage Windows installer for server version 0.9.5

Posted by Sachin Garg on 8th November 2005 | Permanent Link

IIPImage project by Denis Pitzalis is a web client/server system for viewing very high resolution (even gigapixels) images and is designed to be able to work efficiently even over slow dialup connections. The server is an webserver fastcgi plugin and images are viewed via a Java or Javascript client.

Windows installer for server version 0.9.5 was released recently. The screenshots and demo look impressive.

Some excerpts from the website:

By using multi-resolution tiled TIFF images, the server is able to quickly and efficiently send only those parts of the image that the viewer wishes to see at the desired resolution. These parts are dynamically compressed with JPEG and sent to the client. The compression level used can be controlled by the client to optimize the transmission. In this way it is possible to view very large images of several gigabytes in size in real-time over the internet.

The system was originally devised by the National Gallery in London and the University of Southampton for the Viseum (1996) and Acohir (1999) European projects. The aim of these projects was to create a system for viewing very high resolution colorimetric museum images over the internet. In the case of Acohir, to extend the system to handle 3D object sequences. A published paper describing this work is available online. The current versions of the software, though, have been completely rewritten since then.
