Comments on: The Internet’s Largest Image Online - 86400 x 43200 pixels! http://www.c10n.info/archives/386 All about the most recent compression techniques, algorithms, patents, products, tools and events.

I think DICOM supports all major standards like JPEG, Jpeg-LS and Jpeg-2000, but medical industry hates lossy compression, so are jpeg and lossy jp2 will be out of picture, or are they still used? As far as I know, IIP uses tiles (pyramidal tiffs?). Can jpeg2000's progressive features help in such zoomify type applications or are tiles an easier/better way to go? That sounds interesting.

They and we both worked on an IIP-based image server at MGI Software a few years back, and also use JPEG tiles. We're soon transitioning to our own image server, since the medical industry has some specific needs; at that time, we'll have a new large-image format. We're also developing DICOM storage and communication standards for whole-slide images such as you saw. Currently, Zoomify (www.zoomify.com).

I noticed a couple of interesting images at the link you provided. What formats/systems are you using to store and allow viewing of these images?

There are thousands of considerably larger ones from dozens of companies. Actually, it’s probably only about the 10,000th largest image online.
