METHOD OF INTEREST POINT MATCHING FOR IMAGES
First Claim
Patent Images
1. A computer implemented method for point matching comprising:
- (a) providing a pair of images captured;
(b) selecting first and second sets of interest points from the images;
(c) constructing a control network of super points for each set of interest points;
(d) assigning a position, with respect to the closest network control point of each control network, to other interest points on the images;
(e) locating conjugate points for each other interest point of each set based on its assigned position; and
(f) adding the conjugate points to the control network.

Abstract
A computer implemented method for point matching comprising providing a pair of images captured, selecting first and second sets of interest points from the images; constructing a control network of super points for each set of interest points; assigning a position, with respect to the closest network control point of each control network, to other interest points on the images; locating conjugate points for each other interest point of each set based on its assigned position; and adding the conjugate points to the control network.

9. A computer implemented method for point matching for a pair of images comprising:
-
(a) constructing two control networks using points from the images; (b) assigning a relative position to control network points; (c) conducting a correspondence search for points of the control networks; (d) selecting a root and a start point for each control network wherein the root is the point within the network with the most number of correspondences; (e) grouping interest points; (f) constructing a sub-control network from each control network; (g) assigning a relative position to sub-control network points; and (h) generating a further control network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
