碩士 === 國立中正大學 === 電機工程研究所 === 104 === This paper presents the 2D to 3D conversion technology based on background multi-sprite model, the video is divided into foreground and background, and separately through different algorithms to generate the depth information and combine to the depth map. First, we segmentation key-frame to foreground and background by graph-cut, and using label propagation and GMM to get the non key-frame foreground/background segmentation result.In foreground location, we using block matching to propagation foreground depth map from key-frame.In background, we combine the background at all frames into multi-sprite model, after user draw the depth map of the model, we can get the background depth map at all frames. Finally, we combine foreground and background depth map into the final depth map.
