Can anyone shed light on JPEG2000 standards. It is a Lossless compression, and preserves the image quality as original, compared to current JPEG.
I would like to hear some comments and opinions.

I've seen a couple of examples and it is absolutely amazing.
For those guys who use digital cameras, just if you use de the RAW or TIFF format it really can have some interest. Once it preserves the original definition but a very low size file for storage. But the question is who will first put this format in cameras. The high quality of this format and the small file size that he produces is the ideal format to use in one digital camera. When I think that a TIFF image in my camera produces a 14Mb file and it takes about 30 seconds to be able to shot again, I stay in chicken skin

I believe Canon is one of the jpeg2000 founding members, and it is on that committee. So i will be looking forward to see new products from Canon, and who knows, they might provide firmware upgrades to all existing Canon Digital Cameras to store jpg2000 format..

Just a note, I don't think JPEG2000 is lossless. It just uses different mathematical base functions (wavelets). I've worked on wavelet compression, and, although I don't know JPEG2000 by heart, I can tell that the wavelets reduce the annoying artifacts of JPEG.
