Grand Image Compression Challenge at ICIP 2016

For most purposes, image compression is a solved problem.

I assume this challenge exists to create a new image compression format. But I don't see any reason why JPEG2000 doesn't happen again - a new format that almost no one adopts. JPEG was simply good enough.

Although 12-bit color depth with JPEG comparable compression levels would sure be nice.

Holy shit do I strongly disagree with this.

Exactly: there are so many features - like higher bit depth, alpha transparency, different colour spaces - missing form JPEG.

IIRC, JPG2000 wasn't adopted because back in the day we only had Internet Explorer, which required a special plugin, it was too slow, and there weren't many export options.

BPG and FLIF are good contenders in the lossy/lossless area though.

I agree new features would be nice. Like alpha transparency like you mentioned. Or how about cool things like depth or normal maps? I just think almost no one cares. We represent 0.1% of the population.

The last new image format to be universally adopted was PNG in 1996. A lot of entrants have tried ever since, but I think it'd be fair to say none of them mattered the slightest.
