Abstract : Novel view synthesis methods consist in using several images or video sequences of the same scene, and creating new images of this scene, as if they were taken by a camera placed at a dierent viewpoint. They can be used in stereoscopic cinema to change the camera parameters (baseline, vergence, focal length...) a posteriori, or to adapt a stereoscopic broadcast that was shot for given viewing conditions (such as a movie theater) to a different screen size and distance (such as a 3DTV in a living room). View synthesis from stereoscopic movies usually proceeds in two phases: First, disparity maps and other viewpoint-independent data (such as scene layers and matting information) are extracted from the original sequences, and second, this data and the original images are used to synthesize the new sequence, given geometric information about the synthesized viewpoints. Unfortunately, since no known stereo method gives perfect results in all situations, the results of the first phase will most probably contain errors, which will result in 2D or 3D artifacts in the synthesized stereoscopic movie. We propose to add a third phase where these artifacts are detected and removed is each stereoscopic image pair, while keeping the perceived quality of the stereoscopic movie close to the original.
