My code is showing the following:
Warning: Integer operands are required for colon operator when used as index
Y=int32(noise);
Y=int32(yn);
X=int32(xn);
[xn,yn] = ginput(1);
noise = img((yn-2):(yn+2), (xn-2):(xn+2));
noise = mean(noise(:));
img = img - noise;
It is showing the error in 5th line noise = img((yn-2):(yn+2), (xn-2):(xn+2));
Please help
