Outline of Final Research Achievements

We developed signal processing algorithms and video restoration systems for video restoration of documentary films. The proposed restoration algorithm consists of a frame stabilizing method, a flicker removal method, a blotch removal method and a line scratch removal method. The proposed frame stabilizing method estimates parallel displacement and rotation with high accuracy, and removes them. In images of 1,024×1,024 pixels, the estimation error of a rotation angle of the proposed method is 0.3 times than that of the conventional method.
