How do you compare the two images using MATLAB program I am on my project retrieve images and you write code comparison between images using correlation, but there is a problem in the code does not give me incorrect results for comparison please help
count=0;
t=0;
x=imread('D:\Image Retrieval\2.bmp');
a=rgb2gray(x);
srcFiles = dir('D:\Image Retrieval\*.bmp'); % the folder in which ur images exists
for i = 1 : length(srcFiles)
filename = strcat('D:\Image Retrieval\',srcFiles(i).name);
k = imread(filename);
count=count+1;
b=rgb2gray(k);
c=corr2(a,b);
if c==1
imwrite(k,'C:\Users\saba\Desktop\images\image1.jpg');
t=t+1;

disp('tow image are not simalr');
end
end

Jasmine - what results are you getting? What do you expect the results to be? Note that you are comparing the output of corr2 to one which is not always valid especially when using single or double precision numbers. What values of c do you observe?

Are you taking same two images as input? If you are doing so, your statement make sense.
You have asked same question here http://www.mathworks.com/matlabcentral/answers/268393-how-do-you-compare-the-two-images-using-matlab-program
