避免卷积自适应码书搜索算法在G.722.2中的应用

Journal Title: Science Paper Online - Year 2010, Vol 5, Issue 2

Abstract

介绍了ACELP的基本原理，讨论了G.722.2算法中自适应码书搜索算法，并省去了自适应码书搜索中的卷积运算，因此降低了这一部分的计算量。仿真结果表明，该方法既保持了G.722.2算法合成语音的质量，又使其复杂度大幅度下降。

基于NSCT的遥感图像融合性能评价及分析

为了寻求比小波变换更加有效的图像多分辨率分析方法，提出了一种基于非采样Contourlet变换(NSCT)和区域特性选择的遥感图像融合方法，并对NSCT在遥感图像融合中的性能及计算复杂性进行了深入分析。通过与离散小波变换(DWT)和采样的Contour...
