JPEG 9 new lossless JPEG standard

There is a new lossless JPEG standard released just now:
http://www.infai.org/jpeg

Does anybody know more (performance, compression etc.)?

So what ever happened to jpeg2000? It had that feature and a lot of
others.

No idea. What compression ratio did you get with lossless JPEG 2000?

Perhaps the following will be of some usefulness:

There were questions about whether patents covered some of the details,
and as a result it was not widely implemented, and never became common.

Performance will be better than the original lossless JPEG (which was
pretty terrible and in practice almost never used outside a handful of
niche markets). PsPro8 will write a JPEG lossless file and give it the
..JPG extension thus crashing almost every other JPEG decoder.

JPEG came to always mean lossy JPEG in common usage and I hope that IJG
are giving their new format a distinctive name like .JPGL to avoid
codecs crashed by a format that they can't make sense of a la PsP8.

The new standard probably gives compression for 24bit rgb images broadly
comparable with or if they have done it right slightly better than PNG.
I have not had time to play with the new release yet.

JPEG2000 is used in the digital cinema DCP format.

Any application which crashes because the content of a file doesn't
match what it expected due to the file's filename extension is broken.

As is an operating system that solely relies on filename extensions to
figure out file type.

I agree, but Microsoft and the commonly used IJG codec both baulk on
Lossless-JPG streams with a .JPG extension. Malformed JPG files have
been used as a way to vector hostile executable code in the past. It
confused end users no end since they have .JPG files that the decoder
refuses to decode and in some cases for older codecs actually crashes.

Relevant prior art is the JPEG-LS sceme called LOCO by HP

I hope JPEG9 shows how it compares on the same test data.
These are used for some scientific image telemetry

JPEG2000-part 6 is a KEY part of google's PDF files
for books.
