Graphics & Media Lab CMC of Lomonosov Moscow State University has about 10 years’ experience in comprehensive analyzing of compressed video. In March 2013 Graphics & Media Lab has released its first report on stereo films quality assessment. This first report presented our evaluation results and overall quality comparison of 5 stereo films.
After a very successful release of Avatar the interest to stereo 3D films endures now a bad slump. Some people even think that the 3D is dying and has no future. This decline of 3D demand has a serious background: many movie goers experience headache and eyestrain while watching a stereo film.
The Lab decided to analyze the stereo films, captured with stereoscopic camera systems and to investigate the potential reasons of the irritating annoyance. The main examined problems, discovered during the film analysis:
-
excessive horizontal disparity
-
vertical disparity
-
color mismatch (see Image #1)
-
sharpness mismatch
We’ve got a lot of positive comments from professional stereographers on our first report and were encouraged to continue the work on stereo film evaluation. We are planning to publish in the 2nd half of 2013 another three reports and invite the stereographers for cooperation.
Now we have a pleasure to share with the industry professionals our second report on stereo film quality analysis, also including five 3D movies filmed in stereo:
-
Dolphin Tale
-
Drive Angry
-
The Three Musketeers
-
Hugo
-
Sanctum
In the overall comparison of the examined films we compare 3D movies from the 1st and 2nd reports, altogether 10 films.
Depth Budget
Take a look at the depth budget (see the Image #2): 3D films created in 1994 have a big depth budget; the movies from 2011-2012 years have a big negative parallax. ‘Hugo’ has a lot of objects before the screen, on the contrary, in ‘The Three Musketeers’ all objects are behind the screen.
