function_mc_projectionpsf.m

对图像进行local approximation处理的技术,应用于图像去模糊中.

function [y] = funciton_MC_ProjectionPSF(x, delta)

% projection_PSF

[a1,a2]=size(x); aa1=ceil((a1+1)/2); aa2=ceil((a2+1)/2);
y=zeros(size(x));
xx=x(aa1-delta:aa1+delta,aa2-delta:aa2+delta);
y(aa1-delta:aa1+delta,aa2-delta:aa2+delta)=xx;
