Is uncompressed dead?


3


Compression is not dead because ...

o ... of abundance in computing & information


4


But some compression approaches can die if ...

o ... not well managed!


5


Compression game in the last 3 decades

Increase complexity (because of abundance

in resources)

Get better compression

Advanced Image Coding (AIC)

• Advanced Image Coding– Part 1: Guidelines for codec evaluation– Part 2: Evaluation procedure for assessing visually lossless coding– Part 2 AMD1: Evaluation of high dynamic range content– Part 2 AMD2: Evaluation of image sequences

• Call for information issued in February 2015 to receive information on next generation still image compression with superior compression efficiency, as well as other useful features needed in future multimedia applications

• PCS 2015 Feature Event - Evaluation of current and future image compression technologies

• ICIP 2016 Image Compression Grand Challenge - Evaluation of innovative ideas for image compression technologies when compared to existing standards.

Result of this compression game …

Increasingly complex systems...But we seem to be happy aboutit and continue on this trend exclusively!

IP policies in compression standards

oSome standards encourage license bearing compression technologies as opposed to freely usable

Result of this compression game …

Extensions based on an already complex baseline make codecs even more complex!

JPEG approach to standardization

o Baseline compression standard should be license fee free and royalty fee free

o Extensions could include IP with RANDo This avoids push to overload baseline compressiono Leaves the choice to the market!
