| Abstract(in English) | In recent motion-compensated video coding, an adaptive interpolation filter method that can achieve high prediction performance in motion compensation has been proposed. In this method, a horizontal or vertical filter is used to interpolate a pixel at a half-pel position. However, there should still be room for further prediction improvement because the method leaves design freedom for the filter window. From the point, we propose a method that changes the shape of the filter window with the moving object adaptively according to the motion vector. Finally, we show that the proposed method can reduce the total bit rate with the same PSNR as compared to the conventional method. |
