代码说明:

用于归一化均方误差问题的求解,代码可用,有需要的直接下载即可。 % % 计算均方根误差:含噪图像每个象素点与原始图像间误差的平方和的均值的平方根 % %计算结果,rms等于去噪后的噪声标准差 % % Calculate RMS error between result and original % % Idiff = imsubtract(base,result); % get error values % % Idbl = double(Idiff); % convert to double for arithmetic % d_idbl=block_im(Idbl,8); % for i=1:8 %     for j=1:8 %         Isqrd{i,j} = d_idbl{i,j}.^2; % square each pixel %     end  % end

    研一上学期,学校开了数值分析这门课,而且要求用matlab进行上机试验,经过一段时间的学习,对matlab有了最初步的了解,结合所学课程,废了好大的劲才编了几个小程序,希望对后来学习的人有点帮助。(Kenichi last semester, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, after a period of learning, of matlab with the most basic understanding, combined with the course, the repeal of several large series劲才a few small programs, and they hope to learn a little bit later to help.)
