| Abstract(in English) | This paper presents a method for simultaneous restoration and resolution enhancement of blurred video sequences. In the proposed method, prior probability distributions, which are necessary for MAP estimation scheme of high resolution video sequences, are estimated by utilizing intensity gradient in each region. Therefore, the proposed method avoids the reduce of intensity gradients and preserves sharpness in edge regions. On the other hand, the proposed method avoids the increase of intensity gradients in smooth regions from the motion blurred frame in order to reduce ringing artifacts. Then the proposed method simultaneously performs accurate restoration and resolution enhancement. |
