摘要：
In this paper, we present a novel semi-automatic method for converting monoscopic video to stereoscopic video. An efficient interactive image cutout tool is first used to segment the object-of-interest in the key frames. Then, we assign the initial depth information to the segmented objects. These objects are tracked in the whole video sequence through a bi-directional KLT (Kanade-Lucas-Tomashi) algorithm. In addition, depth interpolation is employed to produce the depth information in the non-key frames. Finally, stereoscopic video is synthesized in consideration of different 3D display types. The experimental results show that our method can fulfill 2D to 3D video conversion both reliably and efficiently.
