Description: Functions for converting time series of spatial abundance
        or density data in raster format to vector fields of population
        movement using the digital image correlation technique. More
        specifically, the functions in the package compute
        cross-covariance using discrete fast Fourier transforms for
        computational efficiency. Vectors in vector fields point in the
        direction of highest two dimensional cross-covariance. The
        package has a novel implementation of the digital image
        correlation algorithm that is designed to detect persistent
        directional movement when image time series extend beyond a
        sequence of two raster images.
