中文说明：应用背景 ； ；剪切波变换，这是一个很好的本地化和优化稀疏有一个简单的数学构造与快速算法实现。这些优点使剪切波变换的一个有吸引力的候选人图像表示关键技术（一）对噪音图像进行分解。（b）获得不同子带和不同采用方向滤波方向剪切波系数。
English Description：
Application background shearlet transform which is well localized and optimally sparse has a simple mathematical construction and a fast algorithmic implementation. These advantages make the shearlet transform an attractive candidate for image representationKey Technology (a) To decompose the noisy image. (b) To obtain different subbands and different direction shearlet coefficients by using the direction filtering.
