iat_surf_correspondences

[POINTS1, POINTS2] = iat_surf_correspondences( IMAGE1, IMAGE2, ANGLE_RATIO)
iat_surf_correspondences returns the coordinates of matched keypoints of images IMAGE1 and IMAGE2. After extracting SURF descriptors [1] from images, it obtains matches so that minArcCos<ANGLE_RATIO*secondMinArcCos (inverse cosine of normalized correlation between vectors is used)

Input arguments

IMAGE1 First image
IMAGE2 Second image
ANGLE_RATIO Angle ratio for matching descriptors (see the documentation of iat_match_desciptors)

Output arguments

POINTS1 SURF locations in IMAGE1 (see the documentation of iat_surf)
POINTS2 Correspondences of POINTS1 in IMAGE2
