摘 要
視頻分辨率變換在多媒體領(lǐng)域有著非常廣泛的應(yīng)用，在傳統(tǒng)的插值算法中由于對(duì)圖像邊緣活紋理等細(xì)節(jié)信息考慮不足常常導(dǎo)致插值后圖像出現(xiàn)模糊或鋸齒的現(xiàn)象,所以論文對(duì)H.264／AVC及AVS進(jìn)行了詳細(xì)的分析 。本論文的主要目的就是比較H.264與AVS插值算法，測(cè)試他們?cè)趫D像處理上的優(yōu)劣，利用MATLAB這一工具編寫程序?qū)ν粓D像進(jìn)行處理。
本文分別從運(yùn)算復(fù)雜度和性能兩個(gè)方面進(jìn)行了比較，在復(fù)雜度的分析中引入了復(fù)雜度分析模型,該模型從硬件設(shè)計(jì)的角度合理地量化了兩種插值算法的復(fù)雜度。在比較兩種插值算法的性能上,根據(jù)插值的運(yùn)算特性給出了性能的評(píng)估指標(biāo)。用上述復(fù)雜度模型和性能指標(biāo)對(duì)H.264和AVS的插值算法進(jìn)行分析和比較,實(shí)驗(yàn)結(jié)果表明H.264具有較好的性能,而AVS的性能開銷比略好于H.264 。

H.264 interpolation algorithm with AVS comparison
Abstract
Video resolution transform in multimedia field has a very wide range of applications, in traditional interpolation algorithm for image edges due to live texture detail information consider deficiency often result in interpolation fuzzy or after images appear serrated phenomenon so papers on H.264 / AVC and AVS were analyzed in detail. The main purpose of this paper is to compare with the AVS and H.264 interpolation algorithm, test their in image processing, advantage and disadvantage of the MATLAB this tool programming for the same image processing.
This paper respectively from two aspects of computing complexity and performance are compared, and the analysis of the complexity introduced into the complexity analysis model, this model from the hardware design Angle properly quantify two interpolation algorithm complexity. In comparing two interpolation algorithm performance, and according to the operation characteristics are given interpolation performance eva luation index. With the complexity of model performance index and H.264 and AVS interpolation algorithm analysis and comparison, the experimental results show that the H.264, and has better performance than the AVS performance overhead is slightly better than H.264.
