曲波变换阈值去噪方法是一种有效的随机噪音压制方法,其去噪效果取决于阈值的选取,且存在过度平滑和环绕效应2种固有缺陷。各向异性扩散滤波方法是一种基于热扩散偏微分方程的边界保持的滤波方法,适用于信噪比较高的地震纹理图像,往往用于图像增强。基于对曲波变换阈值的分析,充分结合2种去噪方法的优点,提出了一种有效的联合去噪算法,避开了曲波阈值选取的困难,实现了边界和振幅的保持,改善了曲波变换阈值方法的缺陷。通...

Due to their coarse horizontal resolution, presentday climate models must parameterize deep convection. This
paper presents single-column simulations of deep convection
using a probability density f...
