Abstract—Reconstruction of real object often involves branching contour cases. An effective technique is required to determine the correct corresponding sub contour between two connected contours. This is to ensure the accuracy of the resulted image. This study has introduced a contour matching method using the similarity of the sub contour centroid value. The technique is fast enough equivalence to the requirement of reconstruction technique which has to be time and space effective. The matched sub contours then are connected by introducing an intermediate contour called as composite contour. The technique has been applied in the reconstruction of human head and Stanford bunny from CT images. Beta-spline was employed as the fitted surface as this surface has capability to give smoothed and accurate result.
