Abstract:
The H.264/AVC video coding standard supports motion-compensated prediction with quarter-pel accuracy of motion vectors. In the case of fractional-pel motion vector, pixels at fractional positions have to be interpolated. In an interpolation scheme, computational complexity and coding efficiency are the most important criteria. In order to enhance both the computational complexity and coding efficiency for various textures of videos, we propose a new interpolation scheme using multidirectional filters. Experimental results show that our proposed scheme outperforms other schemes, including the H.264/AVC standard and the latest interpolation schemes, in terms of complexity and coding efficiency.1
