剪切波变换工具，使用剪切波变换实现降噪滤波等各种功能-Shear wave conversion tool with shear waves transform various functions, such as noise filtering

利用剪切波变换的方向性和多尺度特性，在剪切波变换域中进行阈值降噪处理(Using the directional and multi-scale characteristics of shearlet, the threshold denoising is performed well in the shearlet transform domain)

通过剪切波变换对2D图片进行降噪分为GPU运行和正常运行 可调通。
