Description
Summary:We propose a novel method of stereoscopic video blending, targeted at achieving temporal disparity and color consistency. Video blending is one of the most frequent and important tasks in video editing, which is also true in stereoscopic video editing. However, it is more difficult to achieve temporally consistent blending for stereoscopic videos compared with blending of monocular videos, since there is more channel, namely disparity, to be considered except color channels in stereoscopic videos. Toward this end, two algorithms are proposed in this paper for temporally consistent videos blending. One is a temporally coherent mask propagation mechanism for selecting a source video patch clip from the source stereoscopic video; and the other is a temporal blending algorithm, which seeks to adjust the shape of the source video patch clip so as to keep consistent with disparities of the target stereoscopic video. We show various results on numerous examples to demonstrate the effectiveness and efficiency of our method.
