P +% is a 3xK matrix specifying the indexes (X,Y,S) of the points of +% extremum of the octave OCTAVE. The spatial indexes X,Y are integer +% with base zero. The scale index S is integer with base SMIN and +% represents a scale sublevel in the specified octave. +% +% The function returns a matrix Q containing the refined keypoints. +% The matrix has the same format as P, except that the indexes are +% now fractional. The function drops the points that do not satisfy +% the strength and peakedness tests. +% +% See also SIFT(). + +% AUTORIGHTS +% Copyright (c) 2006 The Regents of the University of California. +% All Rights Reserved. +% +% Created by Andrea Vedaldi +% UCLA Vision Lab - Department of Computer Science +% +% Permission to use, copy, modify, and distribute this software and its +% documentation for educational, research and non-profit purposes, +% without fee, and without a written agreement is hereby granted, +% provided that the above copyright notice, this paragraph and the +% following three paragraphs appear in all copies. +% +% This software program and documentation are copyrighted by The Regents +% of the University of California.
