Restoration method of missing image data using modified optical flow

This paper proposes a restoration method of still images including missing pixels by a modified optical flow, which is different from the traditional flow. For successful restoration, the proposed method introduces a new parameter into the selection scheme of the optimum optical flow, which can represent how much reliable the obtained flow is; and based on this parameter, highly reliable optical flows are mainly used in the image restoration. The proposed method consequently achieves more accurate restoration than the previous method does especially in the edge area.
