      • createTargetHisto

        double[] createTargetHisto​(smile.math.matrix.SparseMatrix alpha,
                           org.locationtech.jts.geom.Envelope bbox)
        Returns a histogram representing the rows of the sparse input matrix.
        Parameters:
        alpha - The sparse matrix representing the area of interest to create the histogram from the rows.
        bbox - The area that is represented by alpha.
        Returns:
        The histogram of the input matrix.

      • createCandidateHisto

        double[] createCandidateHisto​(smile.math.matrix.SparseMatrix alpha,
                              org.locationtech.jts.geom.Envelope originalBBox,
                              org.locationtech.jts.geom.Envelope candidateBBox)
        Returns a histogram representing the rows of the sparse input matrix.
        Parameters:
        alpha - The sparse matrix representing the area of interest to create the histogram from the rows.
        originalBBox - The original object area used to adjust weights by how much the candidate needs to scale to match the original.
        candidateBBox - The candidate area that is represented by alpha.
        Returns:
        The histogram of the input matrix.
