ScSR Jianchao Yang 的基于稀疏表示的单幅图像重建的原始代码

Jianchao Yang 的基于稀疏表示的单幅图像重建的原始代码，先将高低训练图像分块，再将块训练成高低字典，将测试图像映射到低字典上，得到系数，再乘以高子典就得到最后的图像。对学习超分辨率同学的参考作用很大

function [im_h] = backprojection（im_h im_l maxIter）

[row_l col_l] = size（im_l）;
[row_h col_h] = size（im_h）;

p = fspecial（‘gaussian‘ 5 1）;
p = p.^2;
p = p./sum（p（:））;

im_l = double（im_l）;
im_h = double（im_h）;

for ii = 1:maxIter
    im_l_s = imresize（im_h [row_l col_l] ‘bicubic‘）;
    im_diff = im_l - im_l_s;
    
    im_diff = imresize（im_diff [row_h col_h] ‘bicubic‘）;
    im_h = im_h + conv2（im_diff p ‘same‘）;
end
