MATLAB: Corner detection on chessboard

corner detection

 I = checkerboard(100,2,2);
 C = corner(I);
 ??? Undefined function or method 'corner' for input arguments of type 'double'.

Is this error is due to version problem.?

I am currently using MATLAB R2008b.

No corner function is shown in help menu..

MATLAB: How to create a chessboard

I am assuming that you are using plot function to create the chessboard, which is resulting in bands in the output. Instead of it, use imshow function as following :

M = 7680;
N = 4320;
C = 8;
F = 8;
I = chessboard3(N,M,C,F);
imshow(I);  
function [a] = chessboard3(N,M,C,F)
L1 = floor(M/C);
L2 = floor(N/F);
k = 1;
for m=1:L1:M
    for n=1:L2:N
        a(m:m+L1-1,n:n+L2-1)=ones(L1,L2)*(cos(k*pi));
        k=k+1;
    end
    k=k+1;
end
end

Refer following documentation to know more about imshow function: imshow
