1% SIFTREFINEMX Subpixel localization, thresholding and on-edge test
2% Q = SIFTREFINEMX(P, OCTAVE, SMIN) refines, thresholds and performs
3% the on-edge test for the SIFT frames P extracted from the DOG
4% octave OCTAVE with parameter SMIN (see GAUSSIANSS()).
5%
6% Q = SIFTREFINEMX(P, OCTAVE, SMIN, THRESH, R) specifies custom
7% values for the local maximum strength threshold THRESH and the
8% local maximum peakedeness threshold R.
9%
10% OCTAVE is an octave of the Difference Of Gaussian scale space. P
11% is a 3xK matrix specifying the indexes (X,Y,S) of the points of
12% extremum of the octave OCTAVE. The spatial indexes X,Y are integer
13% with base zero. The scale index S is integer with base SMIN and
14% represents a scale sublevel in the specified octave.
15%
16% The function returns a matrix Q containing the refined keypoints.
17% The matrix has the same format as P, except that the indexes are
18% now fractional. The function drops the points that do not satisfy
19% the strength and peakedness tests.
