An Efficient SIMD-based Quarter-Pixel Interpolation Method for H.264/AVC
نویسندگان
چکیده
Many media processors which support SIMD (Single Instruction Multiple Data) instructions have been widely used for digital signal processing and multimedia applications. In particular, a set of SIMD instructions is very effective in video applications which require both simple operations and short data types, mostly 8-bit or 16-bit samples. This paper proposes the fast quarter-pixel interpolation of the H.264/AVC, which can be implemented with the Intel SIMD instructions. The implementation of the proposed method is approximately six times faster than that of the JM software for the H.264/AVC quarter-pixel interpolation operation which needs multiple bilinear and 6-tap filtering.

ETRI Journal, Volume 30, Number 4, August 2008 The H.264/AVC standard has adopted new coding tools such as intra-prediction, variable block size, motion estimation with quarter-pixel-accuracy, loop filter, and so on. The adoption of these tools enables an H.264/AVC-coded bitstream to have more information than was possible with previous standards. In this paper, we propose an effective spatial ...

H.264/AVC [1], which is a recently published video coding standard, was developed and has been updated by Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG. The H.264 encoder, similar to that of the existing video standards such as ISO/IEC MPEG-1, MPEG-2, MPEG-4, ITU-T H.261, H.263 [2], is composed of a temporal model, a spatial model, and an entropy encoder. The runtime of the temporal mod...

Fractional motion estimation (FME) is an advanced feature adopted in H.264/AVC video compression standard with quarter-pixel accuracy. Although FME could gain considerably higher encoding efficiency, sub-pixel interpolation and sum of absolute transformed difference (SATD) computation, as main parts of FME, increase the computation complexity a lot. To reduce the complexity of FME, this paper p...
