In cooperation with IITP RAS
About the Report
The report presents detailed (305 pages) evaluation results of 5 S3D films, which were converted to S3D format in post-production.
Analysed films |

The report comprises four main parts:
- Thorough description of visual-discomfort potential causes that are mostly specific to 2D-3D conversion (see page from report)
-
Detailed analysis of five films. Each film description consists of two parts:
- Per-frame analysis with charts showing metric values for each frame; (see page from report)
- Visualizations demonstrating artifacts in frames that earned a poor rating according to our metrics (including new visualizations of problems, specific to 2D-3D conversion! See page from report)
-
Overall film comparison. Here go charts depicting the average metric values and distribution of these values in each film. (see page from report).
Some charts showing overall comparison results are presented in the Overall evaluation results section on this page. - Comparison of 2D and S3D versions of analyzed films (see page from report).
Visualization of a frame from The Avengers. It is clearly visible that the utilized background-reconstruction algorithm lacks quality:
Professional stereographers contributed to the analysis with valuable comments and feedbacks.
Contributed Stereographers
(in alphabetical order)
- Robert Black, 3D R&D, 3D Consultant / Stereographer
- Ross Copeland, Online Editor / Stereographer & Colourist, Post Production Consultant

Overall evaluation results
In this section we present selected overall comparison charts. We use two main types of charts:
- Dot chart which depicts average score of each film according to the metric
- Integral histogram which shows distribution of metric values throughout the film
Depth Budget
Comparison of average depth budget
Depth budget distribution analysis
Vertical Disparity
Comparison of average vertical disparity
Color Mismatch
Comparison of average color mismatch
Color mismatch values distribution
