In traditional methods, optimization of control points and foot points are performed in two alternating time-consuming steps in every iteration: 1) control points are updated by setting up and solving a linear system of equations; and 2) foot points are computed by projecting each data point onto a B-spline curve. Our method uses the L-BFGS optimization method to optimize control points and foot points simultaneously and therefore it does not need to solve a linear system of equations or performing foot point projection in every iteration. As a result, the proposed method is much faster than existing methods}, publisher = {Elsevier}, url = {http://approjects.co.za/?big=en-us/research/publication/fast-b-spline-curve-fitting-l-bfgs/}, pages = {448-462}, volume = {29}, edition = {Computer Aided Geometric Design}, }
