求助：matlab设计维纳滤波器去除图像中噪声时的问题 - MATLAB爱好者论坛-LabFans.com

F=imread('f:\xy10082.jpg');
figure(1);
imshow(F,[]);
PSF=fspecial('motion',7,45);
MF=imfilter(F,PSF,'circular');
noise=imnoise(zeros(size(F)),'gaussian',0,0.001);
MFN=MF+noise;
figure(2);
imshow(MFN,[]);
NSR=sum(noise(

.^2)/sum(MFN(

.^2);
figure(3);
imshow(deconvwnr(MFN,PSF),[]);
figure(4);
imshow(deconvwnr(MFN,PSF,NSR),[]);
我想在已知图像中添加运动模糊和高斯噪声，然后用维纳滤波器除去噪声，运行上面的程序后针对MFN=MF+noise出现如下错误：Integers can only be combined with integers of the same class, or scalar doubles. 请问为什么呢？谢谢！
