The function produce a set of features matched through a pair of views.
The selection is driven by the estimate uncertainty extracted from the Fisher information matrix.
The main script if features_matching.m
Usage:
[x1,x2,corr_vec]=features_matching(im1, im2, cal, initsplit, sm_sigma, sigma_max)
Input
im1, im2 : stereo pair. greyscale images
cal : (1=rectified images with epipolar horizontal lines; 0=uncalibrated images )
initsplit : images initial splitting factor; the images are splitted in (initsplit x initsplit) subimages.
sm_sigma : smoothing Gaussian filter SD (1 -:- 3 for normal smoothing)
sigma_max : Fisher index th (1e-2 -:- 1e-4)
Output
x1, x2 : matched points in the left and right images; 2 x N matrices
x1=[u1 u2 ....uN horiz. coord.
v1 v2 ....vN] vert. coord.
corr_vec : match strength
