Automatic Conversion from Monoscopic Video to Stereoscopic Video
First Claim
1. A method for converting a monoscopic video movie passively acquired using a single camera to a stereoscopic video movie, said method comprising generating stereoscopic pairs comprising, for each frame in the original sequence, a transformed original frame selected from said monoscopic video movie and a transformed alternate frame;
- wherein said transformed frames are generated from said original and said alternate frame in said monoscopic video movie by the following steps;
a.) select said original frame;
b.) select said alternate frame such that a considerable, approximately constant parallax is developed between it and said original frame;
c.) calculate the fundamental matrix between said original frame and said alternate frame based on point correspondences between them;
d.) calculate from said fundamental matrix two homography transformations that may stratified said original and said alternate frames;
e.) apply one of said homography transformations to said original frame and the other of said homography transformations to said alternate frame, thereby obtaining two new frames, which are stereoscopic partners.

Abstract
The invention is a method for converting a monoscopic video movie passively acquired using a single camera to a stereoscopic video movie. The method comprises generating stereoscopic pairs comprising, for each frame in the original sequence, a transformed original frame selected from the monoscopic video movie and a transformed alternate frame. The transformed frames are generated from the original and the alternate frame.
