Prewitte边缘算子法(Prewitte Edge Operators)

MLS用於3D曲面變型，可算出較為準確的法向量(This method can be used to 3D surface deformation,can figure out more accurate normal vecter)

3d球坐标 球坐标绘图 直角转极坐标 画三维图( SPHERE3D(Zin,theta_min,theta_max,phi_min,phi_max,Rho,meshscale) plots the 3D profile Zin as a mesh plot on a spherical surface of radius Rho, between horizontal sweep angles theta_min and theta_max and vertical phi_min and phi_max, with mesh size determined by meshscale. )

说明：  使用Matlab实现遥感时空融合算法STARFM(A code for spatio-temporal fusion (STARFM))

图像融合，主要是利用高通滤波方法，ihs变换方法，主成分分析方法，小波方法以及小波+IHS方法。(Image fusion, mainly using high-pass filtering method, ihs transformation method, principal component analysis method, wavelet method and the wavelet+ IHS method.)

实现图像纹理特征的提取，并且完成了该项功能(The extraction of image texture features, and completed the)
