However, due to the lack of 3D contents, 2D-to-3D conversion technique becomes more and more important in the near future. For 2D-to-3D video conversion, the most common way is to generate correspondent depth video from the original 2D video first then synthesizing the desired video by utilizing generated depth videos. The main key point for 2D-to-3D conversion is how to generate the corresponding depth video precisely and efficiently. This thesis proposes an efficient depth maps interpolation method from existing pairs of key frames and depth maps. The proposed method contains forward/backward block-based motion estimation/compensation, block refinement, object refinement, and frame selection mechanism. Experimental results show that the proposed method can successfully and effectively generate depth maps, which will be a great help for 3DTV content generation.
