| dc.description.abstract | B-spline stands as an efficient curve representation because of its properties and it has been widely used in computer aided design and computer graphics. Finding point correspondence between two curves is a fundametal task in b-spline curve matching. A b-spline curve is not uniqely described by a single set of control points. That is, with different choice for placement of the knot points, a different control points can be induced, but still describe the same curve. This condition is worsen if few knots and control points is used for curve matching. Thus, the direct comparison for knot and control points is not appropriate for curve matching. This research proposed an approach that incorporates deformable mapping (deformation energy) and geometric characteristics (strain difference) of spline curve. This method was implemented on plant leaf image. As the result, same species leaves have low total cost as compared to different species leaves. | en |
