隨著立體液晶螢幕的技術逐漸進步,人們將不再需要配戴立體眼鏡即可透過螢幕欣賞立體影像。有越來越多的研究放在如何將影片立體呈現。其中最常見的方式是先做深度的估測,再依深度合成出視差,進而提供我們左、右眼對應的影像,在觀看時產生立體感。然而傳統單張深度影像估測無法應付高畫框頻率的影片需求。本發明旨在提供一個快速生成影片深度圖的演算法,假使某段影片首尾深度圖已知,本發明使用動作估測與補償、貝式分類器、深度調整機制快速生成中間各影格深度,大幅縮減運算時間。 With the recent 3D display technology improvements, people now can perceive 3D effects in 3D display systems without wearing 3D glasses. However, due to 3D contents are not sufficient enough, the 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 the correspondent depth video from the original 2D video first then synthesizing the desired video by utilizing generated depth videos. The main key point for the 2D to 3D conversion is how to generate the corresponding depth video precisely and efficiently. In this paper, we will propose 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 generate the depth maps successfully and effectively
