JPEG2000 to Zoomify Code4Lib Lightning Talk Video Now Available

Thanks, Noel, and everyone else who made the video editions of Code4Lib 2008 presentations possible. I just had a chance to notice that the video from my JPEG2000 to Zoomify Shim lightning talk was online:

Some updates since the post and the presentation were first done. The code that exists in the source code repository now was refactored to use JJ2000 as part of the Sun ImageIO package. We were seeing non-threadsafe problems with Kakadu and thought that using the multithreaded ImageIO package would help. Unfortunately, even with extensive caching, it did not. My next task is to bring Kakadu back into the picture using the threadsafe JNI implementation that is part of the ImageIO-ext project to see if that helps.

JPEG2000 to Zoomify Shim — Creating JPEG tiles from JPEG2000 images

This is a textual representation of a lightning talk done on Feb 26th at Code4Lib 2008. When the video of the talk is up (thanks, Noel!) I’ll link it here, too. The video is now available, and that article includes an update on progress since the this article was posted.

Is JPEG Good Enough for Archival Masters?

On the ImageLib mailing list, Rob Lancefield (Manager of Museum Information Services for Wesleyan University) posted a link to the Universal Photographic Digital Imaging Guidelines (UPDIG) for image creators. The introduction says: “These 12 guidelines — provided as a Quick Guide plus an in-depth Complete Guide — aim to clarify the issues affecting accurate reproduction and management of digital image files. Although they largely reflect a photographer’s perspective, anyone working with digital images should find them useful…. This document, prepared by the UPDIG working group, represents the industry consensus as of September 2007.” The listed members of UPDIG leads one to believe that this is a professional photography group. One thing in the introduction to the guidelines caught my eye, though:

The chapter on archiving now has a discussion of JPEG as an archival format.

Wireless JPEG2000 Video and a Paper on How JPEG2000 Works

Two items of recent note in the JPEG2000 world. The first is the announcement of “the world’s first fully integrated wireless HDTV” that uses JPEG2000 over the air:

The High Definition LCD TV, featuring Pulse~LINK’s integrated CWave® UWB Wireless HDMI technology, will be on display for the first time at the 2008 International Consumer Electronics Show (CES) in Las Vegas, Nevada, January 7-10. [...] With the integration of CWave® Wireless HDMI, digital display products can be mounted anywhere in the room without needing to run data cabling from the TV to the content source, such as a DVR, Blu-ray or HD DVD player, or a live cable or satellite feed. Video data is encoded using the JPEG2000 video codec, the same codec used by movie theaters for “Digital Cinema,” providing a secure high quality HD experience. Pulse-LINK’s Wireless HDMI solution is engineered to be equivalent in both content protection and visual experience to a wired HDMI connection.

Xerox and Library of Congress Collaborate on JPEG2000 for Image Preservation

Xerox and the Library of Congress announced a joint effort last week to study the use of JPEG 2000. This is welcome news! The project is “designed to help develop guidelines and best practices for digital content,” a result that will be most welcome for those of us that want to do the right thing but lack the time and/or technical expertise to pin down exactly what the right thing is. I think it is safe to say that inertia has taken us this far with our collective TIFF-based practice, and even the most conservative preservationist would probably acknowledge that the state of the art has moved in the past quarter century to a point where there might be a better way.

Results of JPEG2000 Activity in the Google Summer of Code 2007

Earlier this year I posted a summary of planned JPEG2000 activity in the Google Summer of Code. As you may recall, there were two project: one mentored by the Mozilla Foundation and another by FFmpeg. This post is a summary of the results of the efforts of the GSoC students.

JPEG2000 in Firefox

Ben Karel, a Computer Science undergraduate student at the University of Delaware, and I have been having a running e-mail conversation about his efforts to bring JPEG2000 to the Firefox browser. He has given me permission to summarize our conversation here.

JPEG XR Could Be Neat, but JPEG2000 is Still Neater

On Tuesday, the Joint Photographic Expert’s Group (a.k.a. “JPEG”) announced a new work item for the standardization of Microsoft’s HD Photo as JPEG XR (XR is short for “extended range” — a reference to its improvement over the original JPEG standard). You can read the publicity details in the Microsoft press release and the JPEG press release, but beyond the public relations pieces I wonder if you are thinking about HD-Photo/JPEG-XR for digital archiving. And if you’re thinking that I’ll bet your wondering about how HD Photo compares with JPEG 2000. As with many things, the devil is in the details, so here is a first, gut-reaction pass at the details.
