"I am very impressed with how well thought out the Kakadu design is and [Dr. Taubman's] grasp of object-oriented programming. It's going to take some time for me to understand a lot of the concepts, but the code is extremely well-documented. Based on my analysis on all the JPEG 2000 implementations out there, Kakadu is *by far* the best solution."

"Kakadu is a well-crafted framework for efficiently compressing, decompressing, and transcoding images using JPEG 2000. It's both a flexible library and a deep tutorial in image encoding. The example programs are clear and the generated images are compatible with other JPEG 2000 implementations. It's clean and useful for ambitious projects."

Subject: [kakadu_jpeg2000] THANK YOU !!!!
Please allow this quick note of praise for Kakadu V5.2.
Thus far, all I have been trying to do is view JP2 files; in particular, several maps from the US Library of Congress' "American Memory" site. The LoC suggests three different viewers…Of the three, Kakadu is, by far, the best and fastest on my li'l 128K RAM relic.
So a hearty "thank you" to Dr. Taubman (I hope that's correct) and anyone else involved! I look forward to learning more of Kakadu's functionality in the near future.

[kakadu_jpeg2000] Building Kakadu version 5.2.6 under Mac OS X succeeds
I am pleased to report that Kakadu version 5.2.6 compiles successfully under Mac OS X 10.4.8, on Apple PowerPC G5, and Apple Intel Macintosh computers.

Re: Fragmented compression using kdu_stripe_compressor
Hello David (Taubman)
Thanks a lot for the help, I will try to implement this immediately.
As I made some tests using kdu_compress.exe, I have another question
…
Thanks

Re: [kakadu_jpeg2000] ADV202 and Kreversible attribute
Thanks for that David,
I'll certainly look into doing as you've suggested - at least when
deadlines are a little less pressing :)….

Re: Problem in compressing 10-bit RGB image with kdu_compress
Hi David,
Thanks for the "-record" suggestion. It helped me figure out what
the problem was. I was supplying incorrect parameters to Sdims…

Re: [kakadu_jpeg2000] Kakadu version 5.1 compile error
Professor Taubman,
Thank you. After following your suggestion, I was able to successfully compile under Mac OS X all 14 of the Kakadu bin/Darwin-gcc executables.
In my initial tests on a dual processor G5, I am getting a speed up of about 1.75 times... I consider this to be an excellent speed up. Thank you for advancing JPEG2000 technology.
Greg
Dr. Taubman,
… By the way, your information on Qstep, and 16bit support was very helpful and
I was able to get excellent compression with minimal error on large elevation
datasets….
Best regards,
Frank
On 25/9/2001, one of our full commercial customers who would prefer to remain anonymous for the moment wrote:
"after having surveyed available implementations, including commercial offerings, I am convinced that KDU provides by far the best performance in terms of compression/decompression times for JPEG 2000. In addition, I know of no other software that provides the sophisticated access to the codestream that allows for the quick decompression of random portions of the image in an efficient way. The code is industrial strength, providing the most roubust implementation of J2K."
Many our clients have been compressing large GIS images using Kakadu. One has recently compressed a 6 GigaByte image using Kakadu, interactively viewing the compressed image using "kdu_show" over a client-server network using the JPIK protocol. Effective image browsing is apparently possible at transfer rates as low as 100 bytes/second!!
