MSUtils.general.compute_correlation_length.compute_correlation_length(img)

Compute the correlation length of an image using FFT and exponential decay fitting.

Parameters: - img: The input image as a NumPy array.

Returns: - cl: Correlation lengths for each dimension. - aspect_ratio: Aspect ratio derived from correlation lengths. - autocorr: The autocorrelation function of the image.
