Harris角点检测代码， function [ posr2, posc2 ] = harris(image,Thrshold ) %HARRIS Summary of this function goes here I = double(image); %% For each pixel(x,y) in the image calculate the autocorrelation matrix M %% M= [Ix2(i,j) Ixy(i,j);Ixy(i,j) Iy2(i,j)]; f
运动模糊图像的复原中经常要用到点扩散函数psf,该程序实现求取点扩散函数psf，即实现Matlab中的fspecial函数（求psf），你只要设定好参数length和angle就可以了，调用get_psf()- Motion-blurred images are often used to recover the point spread function psf, the realization of the program to strike a point spread function
im = im2double(imread('C:\Users\air\Desktop\2.jpg')); M = size(im,1); h = fspecial('gaussian',5,1); imb = filter2(h,im)+rand(M,M)/10; figure; subplot(121); imshow(imb); subplot(122); imshow(im); Y = fft2(imb); H = fft2(h,M,M); invH = 1./H; idx = fin
