| Abstract(in English) | The restoration of video signals corrupted by the additive noise is important for getting the high quality image and the high compression ratio of video signals. In this paper, we propose the recursive type of video-data dependent weighted average (R-Video-DDWA) filters for restoring video signals corrupted by the Gaussian noise. The proposed filter is a spatio-temporal filter which uses only one previous output frame. The recursive type of filters has strong noise attenuation property, thus, the good results can obtained in still regions. However, motion is more degraded compared to non-recursive type of spatio-temporal filter. To overcome this defect, the proposed method utilizes the motion information for calculating the weight for the previous output frame. Through some simulations, we show the efficiency of the proposed filter from both noise attenuation property and edge/detail preservation property points of view. Furthermore, the proposed filter is excellent at the calculation cost, since, the cost is almost same as spatial filters. |
