Nvidia is showing off a new incarnation of their tech demo. Human expressions rendered in real time close to flawless.
The amazing part is that the original video was made with a very serious graphics card, but now an optimized version is running on a prototype Tegra 5 mobile chip drawing a few watts only.
When sharing the earlier video a few months ago, I found it convincing except for the eyes which were still a bit 'dead'. Nvidia claims to have improved the light refractions in the pupil. Maybe that did the trick, maybe the slightly lower quality of the rendering technology on this mobile chip actually helped but I found this one more convincing than the older one.
Goal reached? Good enough photo-realism or uncanny valley territory?

simply amazing!
After reading your post, I focused on the eyes, one thing that I think isn't quite there yet are the pupils, those do tend to change size much more often with varying facial expressions – Ira's rarely, if ever change.
forgot to ping +Yonatan Zunger who was impressed with the first gen. version. Improved?
+Susanne Ramharter and compared with this one Digital Ira – NVIDIA FaceWorks Human Face TechDemo
hmm, wrong example. Have to run now, but will find a better example of the first gen. video.
I can only recommend that the people working on Ira read Paul Eckman's work on micro-expressions, it's fascinating. Though, it looks in the latest version as though they might have.
