摘 要
视频分辨率变换在多媒体领域有着非常广泛的应用，在传统的插值算法中由于对图像边缘活纹理等细节信息考虑不足常常导致插值后图像出现模糊或锯齿的现象,所以论文对H.264／AVC及AVS进行了详细的分析 。本论文的主要目的就是比较H.264与AVS插值算法，测试他们在图像处理上的优劣，利用MATLAB这一工具编写程序对同一图像进行处理。
本文分别从运算复杂度和性能两个方面进行了比较，在复杂度的分析中引入了复杂度分析模型,该模型从硬件设计的角度合理地量化了两种插值算法的复杂度。在比较两种插值算法的性能上,根据插值的运算特性给出了性能的评估指标。用上述复杂度模型和性能指标对H.264和AVS的插值算法进行分析和比较,实验结果表明H.264具有较好的性能,而AVS的性能开销比略好于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.
