图像修复常用算法，基于偏微分方程的方法，利用扩散模型进行图像修复

function CHANGE=changei（Iijtnum）
%changei是像素表示沿着等照线的变化的函数，这里没有用到拉普拉斯算子，用的是改进算子ASG，tnum 表示的 rgb通道
%x=laplacei（Ii+1j）-laplacei（Ii-1j）;
%y=laplacei（Iij+1）-laplacei（Iij-1）;
%x=double（I（i+2j）+I（i+1j+1）+I（i+1j-1）-4*I（i+1j）+4*I（i-1j）-I（i-2j）-I（i-1j+1）-I（i-1j-1））;
%y=double（I（i+1j+1）+I（i-1j+1）+I（ij+2）-4*I（ij+1）+4*I（ij-1）-I（i+1j-1）-I（i-1j-1）-I（ij-2））;
Ix=0.5*（mavg（Mmavg（I（i+2jtnum）I（i+1jtnum）I（ijtnum））max（I（i+1j+1tnum）I（i+1jtnum））max（I（i+1j-1tnum）I（i+1jtnum）））-mavg（Mmavg（I（i-2jtnum）I（i-1jtnum）I（ijtnum））max（I（i-1j+1tnum）I（i-1jtnum））max（I（i-1j-1tnum）I（i-1jtnum））））;
Iy=0.5*（mavg（Mmavg（I（ij+2tnum）I（ij+1tnum）I（ijtnum））max（I（i+1j+1tnum）I（ij+1tnum））max（I（i-1j+1tnum）I（ij+1tnum）））-mavg（Mmavg（I（ij-2tnum）I（ij-1tnum）I（ijtnum））max（I（i+1j-1tnum）I（ij-1tnum））max（I（i-1j-1tnum）I（ij-1tnum））））;
CHANGE=[IxIy];
