It provides scalability at the bit stream level with good compression efficiency and allowing free combinations of spatial, temporal and quality scalability. In the WD, a uniform up\u2010sampling filter is employed to interpolate the base layer frames. This technique achieves high interpolated precision for both luma component and chroma components, but it results in extremely large encoding time which obstructs it from practical use. This paper proposes an improved up\u2010sampling filter design for spatially scalable video coding. It makes use of a basic characteristic of human vision system and intends to assign different filters for different components. Specifically, current usage of the 6\u2010tap up\u2010sampling filter is only for luma component, but for chroma components, much more simplified filter such as 4\u2010tap filter or 2\u2010tap filter should be used instead. Experimental results show that improved up\u2010sampling filter design reduces the computational complexity significantly with negligible coding loss and bit\u2010rate increases. \u00a9 2008 Wiley Periodicals, Inc.
