[討論] 求影像的均方根誤差(RMSE)
各位好~~
最近求兩張影像的均方根誤差(RMSE)
因為求出來的值很怪異
所以想麻煩版上各位高手 幫忙檢視一下 是不是那裡出了問題
程式如下:
--------------------------------------------------------------------
h1=imread('1.tif');
h2=imread('2.tif');
s=size(size(h1));
if s(2)==2
f1=h1;
f2=h2;
else
f1=rgb2gray(h1);
f2=rgb2gray(h2);
end
G1=double(f1);
G2=double(f2);
[m1,n1]=size(G1);
[m2,n2]=size(G2);
m=min(m1,m2);
n=min(n1,n2);
c=0;
for i=1:m
for j=1:n
w=G1(i,j)-G2(i,j);
c=c+w^2;
end
end
f=sqrt(c/(m*n));
fprintf(1,'RMSE= %7.3f ', c);
