About the Report

The sixth report is dedicated to the analysis of stereo-window violation issue and use of floating windows in various S3D movies. The report presents detailed (415 pages) evaluation results of 10 S3D films, which were natively captured or post-converted.

Analysed films	Examined problems:
The Amazing Spiderman (2012) The Three Musketeers (2011) Pirates of the Caribbean: On Stranger Tides (2011) Dolphin Tale (2011) Drive Angry (2011) The Avengers (2012) John Carter (2012) G-Force (2009) Abraham Lincoln: Vampire Hunter (2012) Clash of the Titans (2010)	Stereo-window violation

The report comprises three main parts:

1. 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.
2. 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.
3. 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.

In appendix we present our analysis of slant floating-window use in selected S3D films and a relatively uncommon technique that we call the letterbox-violation effect.

Professional stereographers contributed to the analysis with valuable comments and feedbacks.
