Jacobi
Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。
若其特征值全为正,则此Jacobi矩阵正定,即它的任何二次型都大于零。并且如果是对称Jacobi矩阵,还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根
det(A-xI)=0(Jacobi)

KNNMeanFilter
说明: 原理:以待处理的像素作为中心,取一个nXn的模板,在模板中选择k个与待处理像素的值最接近的像素,将这k个像素的均值替换原来的像素值。
假设n=3,k=5,调用方法:b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))
