非下采样轮廓波变换，NSCT变换，主要用于图像去噪(Non - down sampling contourlet transform and NSCT transform are mainly used for image denoising.)

说明：  自己实现的BM3D图像去噪算法。它首先把图像分成一定大小的块，根据图像块之间的相似性，把具有相似结构的二维图像块组合在一起形成三维数组，然后用联合滤波的方法对这些三维数组进行处理，最后，通过逆变换，把处理后的结果返回到原图像中，从而得到去噪后的图像。(Image Denosing by Sparse 3-D Transform-Domain Collaborative Filtering.)

说明：  将原图二值化处理后，对二值图像进行腐蚀处理去掉图中主体以外的噪点或小斑迹(After binarization of the original image, the binary image is corroded to remove the noise or small spots outside the main body of the image)

压缩包里面为2个程序，一个是悬链线模拟索的程序，一个是抛物线法模拟的索的程序(Compressed inside of two programs, one cable catenary simulation program, a parabolic law analog cable programs)

影像融合评价程序，计算标准偏差，平均梯度，相关系数，光谱扭曲度等融合指标。(Image fusion evaluation, calculation of standard deviation, average gradient, correlation coefficient, spectral distortions, such as integration targets.)

对微震图像进行去燥，利用同步压缩连续小波变换进行自动微震去噪和起始检测。(Denoising the microseismic image,automatic microseismic denoising and onset detection using the synchrosqueezed continuous wavelet transform.)
