Class Summary

Class	Description
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).
AbstractOctaveInterestPointFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>	Abstract base class for objects capable of detecting interest points within an octave.
BasicOctaveExtremaFinder	A basic concrete implementation of an AbstractOctaveExtremaFinder that searches for local extrema in scale space.
BasicOctaveGridFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>	An AbstractOctaveInterestPointFinder that detects points on a regular grid.
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).
