Comparison of images with matlab

Question

hey

I want to compare two images using matlab and display a message 'it is the same image' or.'sorry , it's not the same image' My program always displays 'it is the same image'.

Mycode is:

i1=imread('001_1_1.fig');
i2=imread('001_1_1.fig');
x1=edge(i1,'canny');
j1=imcrop(x1,[135 90 100 95]);
x2=edge(i2,'canny');
g=0;
xxx=1;
yyy=1;
    for n=1:1:2
        g1=imrotate(j1,n,'bilinear','crop');
        r1=corr2(j1,g1);
        if(xxx<r1)
        else
            xxx=r1;
        end;
    end;
    for n=180:-1:178
        g1=imrotate(j1,n,'bilinear','crop');
        r1=corr2(j1,g1);
        if(yyy<r1)
        else
            yyy=r1;
        end;
    end;
    if(xxx<=yyy)
        r_corr=xxx;
    else
        r_corr=yyy;
    end;
    j2=imcrop(x2,[135 90 100 95]);
        r=corr2(j1,j2);
        if (r==1)
            disp('it is the same image')
            return;
        elseif (r>=r_corr)
            disp('it is the same image')
            return;
        else
            g=1;
        end;

if(g==1)
disp('sorry, it is not the same image')
end;

Answer 1

You're loading two images, i1 and i2 using the following command

i1=imread('001_1_1.fig');
i2=imread('001_1_1.fig');

These images are the same. Therefore, the code will tell you that the two images are the same.
