Method Details

getLaplacian

Mat getLaplacian()

Get Laplacian of Gaussian image (calculated by summation without requiring eigenvalues).

Returns:

getDeterminant

Mat getDeterminant()

Get the determinant for each pixel.

Returns:

getEigenvalues

List<Mat> getEigenvalues(boolean sortByAbs)

Get the eigenvalues, ranked from highest to lowest.

Parameters:

sortByAbs - if true, return eigenvalues sorted by absolute value; otherwise return sorted by value

Returns:

getEigenvectors

List<Mat> getEigenvectors(boolean sortByAbs)

Get the eigenvectors, returned in the same order as the eigenvalues. Vector elements are stored along the 'channels' dimension.

Parameters:

sortByAbs - if true, return eigenvectors corresponding to eigenvalues sorted by absolute value

Returns:
