Demonstration

Kakadu provides a comprehensive implementation of multiple parts of the JPEG2000 family of standards:

1. Kakadu fully implements Part 1, — i.e., ISO/IEC 15444-1 (Core coding tools and JP2 file format)
2. Kakadu implements the vast majority of Part 2 — ISO/IEC 15444-2 (Extended coding tools and JPX file format)
3. Kakadu implements most of Part 3 — ISO/IEC 15444-3 (Motion JPEG 2000)
4. Kakadu implements almost all features of Part 9 — ISO/IEC 15444-9 (JPIP tools for interactive remote browsing)
5. Kakadu fully implements Part 15, — i.e., ISO/IEC 15444-15 (High Throughput JPEG 2000)

Install the “kdu_show” application v7.1 or later on your Windows or Mac OSX platform.

Try out the following links, using iExplorer or Safari. Alternatively, you can open kdu_show and use the File Open URL dialog to enter the URLs embedded in the links below.

(NB: If these do not work, I might need to restart the server on the machine I use to serve them e.g., after a power failure. You can always run your own copy of the client/server tools in your local environment to test it all out).

Read about JPIP (JPEG2000 Internet Protocol) and the Kakadu implementation.

 What can you do? – JPEG2000 and Kakadu offer a very rich and powerful remote browsing experience. You can zoom in and out (try the ctrl-z/cmd-z and shift-ctrl-z/shift-cmd-z keys); you can pan around; you can define focus boxes which you pan around, shrink, widen, etc.; you can browse via the metadata catalog sidebar (JPX images) or via the imagery window; you can click on metadata categories to have the imagery window show you the regions whose metadata belongs to those categories; you can navigate through ontologies via links in the metadata catalog; you can advance the view from frame to frame in the imagery window or via the metadata catalog for multi-frame sources; you can save whatever you have browsed so far to a local file; you can open up a new window of interest (ctrl-D/cmd-D) into the remote file which shares all locally cached content with the first view (of course you can open many such views and maintain separate focus boxes in each); and much, much more.

Note: you should use version 6.4 of “kdu_show” (“kdu_macshow” or “kdu_winshow”) for the best possible browsing experience, especially with the images that contain rich region-of-interest metadata markup.
