Pearson-correlation
在统计学中,皮尔逊积矩相关系数(英语:Pearson product-moment correlation coefficient,又称作 PPMCC或PCCs[1], 文章中常用r或Pearson s r表示)用于度量两个变量X和Y之间的相关(线性相关),其值介于-1与1之间。在自然科学领域中,该系数广泛用于度量两个变量之间的相关程度。它是由卡尔·皮尔逊从弗朗西斯·高尔顿在19世纪80年代提出的一个相似却又稍有不同的想法演变而来的。这个相关系数也称作“皮尔森相关系数r”。(In statistics, Pearson product-moment correlation coefficient (English: Pearson product-moment correlation coefficient, also known PPMCC or PCCs [1], the article used or Pearson s r r representation) is a measure of the two variables X and Y between correlation (linear correlation), a value between-1 and 1. In the natural sciences, the coefficient is widely used to measure the degree of correlation between the two variables. It is made a similar Karl Pearson Francis Galton in the 1880s but made a slightly different idea evolved. The correlation coefficient is also called Pearson s correlation coefficient r .)

USFFTCurvelet
提出了一种结合USFFT Curvelet 变换的各向异性扩散图像去噪模型。它有机结合了Curvelet 变换和各向
异性扩散(P-M扩散)两者的优点。通过P-范数方法选择合适的梯度阈值K,P-M扩散过程通过处理经过Curvelet
变换得到的图像的不同尺度的Curvelet 系数矩阵,实现了建立在对图像多尺度分析的基础上的新P-M扩散模型。
实验表明,新模型的处理结果能有效避免传统P-M 扩散出现的阶梯效应,同时更好地保留图像的纹理和细节。
关键词:图像去噪算法;各向异性扩散;Curvelet 变换;P-M 扩散(Abstract: An image de-noising model by integrating anisotropic diffusion with USFFT Curvelet transform was proposed,
which combined the strongpoint of Curvelet transform with anisotropic diffusion (P-M diffusion). By choosing appropriate
gradient threshold K through p-norms and carrying out the P-M diffusion process depend on the different scale matrixes
of Curvelet coefficient of the image from Curvelet transform iterations, as a result, the improved model made it
possible to carry out the new P-M diffusion de-noising process based on multi-scale analysis of the image. The experiment
results have demonstrated that the model can avert the stair-casing effect in the traditional P-M diffusion effectively
and keep the textures and details of images better.)
