Interface HarrisCornerIntensity<T extends ImageSingleBand>

All Superinterfaces:

FeatureIntensity<T>, GradientCornerIntensity<T>

All Known Implementing Classes:

ImplHarrisCorner_F32, ImplHarrisCorner_S16, ImplHarrisCornerWeighted_F32, ImplHarrisCornerWeighted_S16

public interface HarrisCornerIntensity<T extends ImageSingleBand>
extends GradientCornerIntensity<T>

The Harris corner detector [1] is similar to the ShiTomasiCornerIntensity but avoids computing the eigenvalues directly. In theory this should be more computationally efficient.

corner = det(D) + k*trace(D)²
where D is the deformation matrix (see GradientCornerIntensity), and k is a tunable scalar.

k typically has a small value, for example 0.04.
