HI Steve, Of course, it is difficult to be certain, but I would indeed expect a 4 processor machine to give roughly a 4-fold speedup. Packet generation need...

Hello Dr. Taubman, Following your advise, we bought a copy of Kakadu license and installed on a mac. I still have the same problem. But this time I did more...
If we compress a clip of uncompressed High-Definition video (1080i) by two ADV202s to a motion-JPEG2000 file, and then decompress it by the chips, the output...

Thank you very much. While the compressed video by ADV202 has the ADV202 head instead of MJ2 header. I'm searching for the "timescale" etc. ... 30 to...
Hello all, I own a personal license of the software. Can anyone tell me if the JPEG2000 codec allow random access. I mean I can type in some paramters on my...
It is said that the compressed ADV202 video is Motion-JPEG2000, while the ADV202 head is added. There are two ADV202 chips in our system, one is for Y...
... Hi, since each sub-image has same dimensions, it seams suitable to treat them as tiles. If you are familar with the structure of a compliant codestream, ...

I am using Kakadu v4.3 Kdu_compress.exe to create jpf files on the PC. kdu_show.exe can display these images but PhotoShop CS (with JPEG 2000 plugin)will not...
HI Alec, There is a tremendous amount of random access support -- just look at the demo apps such as "kdu_expand" (-region argument) and "kdu_show" (show...

Hi all, I have a question on error dectection by using kakadu v4.3 or later. For example, by using modes 'restart' and 'erterm' and kdu_compress, we have an...
I am afraid I cannot take any responsibility for what happens in the Alberio software. If they have relied on a particular version of the Kakadu DLL, they ...
HI Lou, I don't know exactly what your jpf files look like, but the Kakadu implementation of JPX is probably much more extensive than that in Photoshop. I may...
