Method Details

getLaplacian

public Mat getLaplacian()

Description copied from interface: MultiscaleFeatures.Hessian

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

Specified by:

getLaplacian in interface MultiscaleFeatures.Hessian

Returns:

getEigenvectors

public List<Mat> getEigenvectors(boolean sortByAbs)

Description copied from interface: MultiscaleFeatures.Hessian

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

Specified by:

getEigenvectors in interface MultiscaleFeatures.Hessian

Parameters:

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

Returns:

getEigenvalues

public List<Mat> getEigenvalues(boolean sortByAbs)

Description copied from interface: MultiscaleFeatures.Hessian

Get the eigenvalues, ranked from highest to lowest.

Specified by:

getEigenvalues in interface MultiscaleFeatures.Hessian

Parameters:

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

Returns:

getDeterminant

public Mat getDeterminant()

Description copied from interface: MultiscaleFeatures.Hessian

Get the determinant for each pixel.

Specified by:

getDeterminant in interface MultiscaleFeatures.Hessian

Returns:

close

public void close()

Specified by:

close in interface AutoCloseable
