In cooperation with IITP RAS
About the Report
The seventh report is dedicated to the analysis of stereo-window violation issue and use of floating windows in various S3D movies. The report presents detailed (333 pages) evaluation results of 10 S3D films, which were natively captured or post-converted.

The report comprises three main parts:
- We thoroughly describe the stereo-window violation effect and how it can be fixed using a floating-window technique. Next we provide a brief explanation of how to understand charts and visualizations in this report.
- We offer a detailed analysis of 10 films. This analysis comprises per-frame charts showing floating-window and closest-object disparities for both the left and right borders of the screen. Visualizations of frames with the most noticeable stereo-window violations are provided under the corresponding charts.
- The report concludes with an overall film comparison. Here, we show charts depicting the noticeability of stereo-window violations and the intensity of floating-window use for each film.
Example of a stereo-window violation
Professional stereographers contributed to the analysis with valuable comments and feedbacks.
