| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Currently, motion compensation (MC) based on precise motion vectors, typically with half-pel or quarter-pel accuracy, is commonly used in video coding schemes. On the other hand, we have proposed a novel MC method which employs motion vectors with integer-pel accuracy and adaptive interpolation filters to compensate various motions. Recently, the method has been extended to use motion-compensated multiple frames at once. In this paper, we combine our method with an overlapped block MC technique using a smoothed window function. Simulation results indicate that the proposed method provides a coding gain of up to 1.0 dB in SNR compared with our previous method. | |
