Abstract : This paper presents a novel algorithm for 2D planar curve recognition based on B-Spline modeling. It combines the advantages of the B-Spline that are continuous curve representation and affine invariant, and the robustness of the CSS matching with respect to noise and affine transformation. It solves the problem of the non-uniqueness of B-Spline in curve matching. A new algorithm, which contains the degree increasing and reduction, is proposed for smoothing B-Spline and constructing the CSS image. This presented method has been tested and experimental results show the good performance of the proposed algorithm.
