Paper Abstract

This paper reports a method to recognize partially occluded objects using the B-spline representation of the boundary. Curve sgements are represented using B-splines which are piecewise polynomial curves guided by a sequence of points. The B-spline control points found from the boundary points is then used to extract local features of the curve. A Hough transform like method is applied to normalize the two curve boundaries using extracted local features. The merit of a match is evaluated using the normalized B-spline control points. The ability of the technique to handle partial boundary information is also demonstrated.
