Hi
I am working of a project where I have to determine the correlation length of some model parameters. This can be related to determining the correlation length in an image. Such as one of the images below:
This is three realizations of spherical Gaussian covariance model with:
Mean = 0.863
Variance = 8e-6
correlation length in horizontal direction = 6 pixels
correlation length in vertical direction = 6*0.3 = 1.8 pixels
I have to approximate the value above from the images (The 3 matrices are attached, p1, p2 and p3). The mean and variance I have determined as follows:
meanValue = mean(mean([p1; p2; p3]));
variance = mean(var([p1; p2; p3]));
But I cannot find a way to determine the correlation length.
Any suggestions will be very much appreciated!!
Thanks in advance.
