AbstractOctaveExtremaFinder<OCTAVE extends GaussianOctave<FImage>>
Class for finding extrema within
Octaves using the approach in
Section 4 of Lowe's IJCV paper (minus the bit on using Brown's interpolation
approach to improve localisation). |
class |
BasicOctaveExtremaFinder
A basic concrete implementation of an
AbstractOctaveExtremaFinder
that searches for local extrema in scale space. |
class |
BasicOctaveGridFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>
An
AbstractOctaveInterestPointFinder that detects points on a regular
grid. |
class |
InterpolatingOctaveExtremaFinder
Implementation of the method described in
"Invariant Features from Interest Point Groups" by Matthew Brown and David
Lowe (http://www.cs.ubc.ca/~lowe/papers/brown02.pdf) for improving the
localisation of interest points detected in a difference-of-Gaussian by
fitting a 3D quadratic to the scale-space Laplacian (approximated by the
difference-of-Gaussian pyramid).
