[Mp4-tech] RE: I Frame Only AVC-H.264 streams?

[Gary Sullivan]

Yasser Syed et al,
There are now (as of a few months ago) four all-Intra profiles in the standard.  SMPTE has also focused some work on that topic.
There have been quite a few published studies of the coding efficiency of all-Intra use of the standard.  The general consensus is that the compression capability is quite good (relative to other well-known designs).  Some people who have published papers on that topic include Detlev Marpe, Ricardo de Queiroz, Touradj Ebrahimi, and Pankaj Topiwala.  Each of those names actually represents a distinct team of people who have published at least one paper on the topic (in most cases, several papers were published reflecting different kinds of test material, different coding configurations, etc.).  I am sure that there have been others who have published on the topic as well.
A new paper was published last month by Alexandre Zaghetto and Ricardo de Queiroz at the IEEE ICIP 2007 conference (just a couple of weeks ago) that I thought was rather interesting.  It focused on the use of QP control to optimize the visual quality of images containing a mixture of text/graphics and natural photographic content.  I believe Marpe et al. have also made closely-related remarks in their work.
Best Regards,
Gary Sullivan
