JPEG2000: Is It The Future Of Imaging?

Posted by timothy on from the yes-but-what-*kind*-of-'movie-stars'? dept.

LISNews writes: "EE Times has a cool story on the pending JPEG2000 standard and how it will change what we see on the Web. They are already thinking wireless: 'The killer app for JPEG2000 is a handheld device combining both Internet applications and wireless access.'" They're also thinking about migration from current formats, smooth degradeability and -- nice to hear -- Open Source acceptance. Try JPEG's own JPEG2000 page for more information and links.

  1. Redundant again! Please reconsider your priorities by orpheus · · Score: 5

    We basicallycovered this all before. Not a whole lot new here!

    Good lord, I'm really getting tired of this! If you guys can't read and remember your own front page (as you've admitted you don't) then it means that you (as individuals) aren't picking topics that you (as a group) find essential reading -- and that's a terrible sign!

    There's so much interesting stuff going on, but they seem to find the same old stories over and over, perhaps 1/3 of the accepted stories are retreads. CmdrTaco et al -- we love you, but maybe it's time to go to a community moderated article selection with occassional "automatically accepted" posts by you guys.

    if you can't remember or even do a search on old topics when picking a new one, you are too overloaded to be doing a good job at the task of selecting topics.

    There are so many other areas where we'd rather have you guys using your impressive talents!

    At the very least, can we see a quarterly thread to select the "best-of" suggestions for improving SlashDot, the way we select questions for interviews? Call it a step towards RMS's view of community-based Open source, if you will, but repeats and other bad thread decisions serve no one, and I like /. too much to let it drift off course without saying something.

  2. Obligitory Porn/Picture Post by citizenc · · Score: 5
    Besides such obvious applications as medical imaging, prepress or photo archives enabled by JPEG2000's lossless-compression feature (meaning no pixels are lost in compression), experts said that where JPEG2000 truly shines for mass market applications is in wireless applications.
    Excuse me.. have we forgotten the MOST IMPORTANT application? Think of just how high the quality of porn will become! I won't have to leave my room for weeks! :)

  3. JPEG2000 Comparison... by frantzdb · · Score: 5
    I recently found this: comparison of JPEG2000 to standard JPEG. The author, Raph Levien, was not too impressed.

  4. Designer's Article on JPEG 2K by mTor · · Score: 5


    If you don't want to read through specs and prefer a down-to-earth explanation of features etc, check this Designer article on JPEG2K and what it will mean to web design of future. Excellent stuff.

  5. JPEG2000 thoughts and questions by jspring · · Score: 5

    As a technical member of the JPEG2000 body, I have to say that sitting in and participating in the meetings was quite an interesting experience. As always, there were a number of technical issues to resolve, but the most heated and often most time was spent on IP issues. The comment in the article, warning about people holding IP crawling out of the woodwork if the standard is successful is definitely one to watch. While I have not been involved in the last couple of meetings, I'm still actively involved in following what has been happening technology wise. The benefit of wavelet compression is not so much in compression quality, but in features. From a file, one can get multiple resolutions, multiple quality levels, selective decoding of a specific region (random access), etc. This should be a benefit in the long run. The article touches on it briefly, but one down side to the new standard is that it is more resoure intensive than the current JPEG even PNG formats -- in memory and cpu power. I suspect it will be a while until we see wireless devices with the resources to handle the format in a general purpose manner. A custom ASIC solution is a possibility, but would a device like a Palm Pilot include one? What are the factors that lead to the improved quality and additional complexity? JPEG2000 is based upon wavelet compression. The standard allows for tiling images, but it is more typical that the whole image is compressed, for most applications. Unlike JPEG, where pixels are grouped into 8x8 blocks, wavelet schemes which operate upon the whole image have a lot more data to play with when it comes to throwing away (quantizing) information. If one were to attempt to use the standard with 8x8 tiles, well, it would not work very well. Because of this increase in data that is part of the working set, the amount of memory needed, when compared with JPEG is, in most cases, much greater. During the JPEG2000 process, a few companies proposed block-based wavelet solutions which would reduce this complexity without sacrificing feature set or even quality. However, they were not included due to concerns over the companies not making the IP available on a free and non-discriminatory basis. There has been a part-2 to JPEG2000 proposed that will allow for the inclusion of technologies which IP is not necessarily free. My question to the group here is, if JPEG2000 takes off and companies and individuals who have not previously declared IP come forward and want royalties, will the standard be hurt? Is there a place for a part-2 which contains IP which is not free? And, what applications does the community here see as being crucial for the adoption of JPEG2000? Good night and enjoy.. -jim
