i need code in matlab

find the correlation coefficient between i1=pout.tif and i2=pout.tif

[Walter Roberson]

pout is not a standard MATLAB class, so pout.tif is not something we would expect to have defined.

i dont know this homework

Answer 1

[Walter Roberson]

Your two inputs appear to be the same (unless pout.tif is a method of a class that implements randomness.) The correlation coefficient will be 1.

Thank you , but I want the code in matlab to confirm the answer

Answer 2

[Walter Roberson]

i1 = rand(100,100);
i2 = i1;
corrcoef(i1, i2)

thank you

Try this:

grayImage1 = double(imread('pout.tif'));
grayImage2 = grayImage1;
cc = corrcoef(grayImage1, grayImage2)
message = sprintf('The correlation coefficients are \n%f %f\n%f %f', cc)
helpdlg(message);
