Medial axis techniques for stereoscopic extraction

摘要

To perform the stereoscopic conversion of Disney's Beauty and the Beast, we developed novel extensions to standard medial axis techniques. Distance transforms, directional influences, and segmentation variations were used with medial axis skeletonization to automatically generate depth maps from the hand-drawn images. Overall, our methods significantly reduced the amount of manual rotoscoping and modeling traditionally required for a stereoscopic conversion process.
