Approximation by NURB curves with free knots
This paper is concerned with approximating noisy samples by NURBS curves with special emphasis on free knots. We consider the knots as unknown parameters so as to find their optimal positions. The original problem which is linear with respect to the weights and the control points but is nonlinear with respect to the knots is reformulated such that the knots are the only variable set. We show ho...
متن کاملOn Local Matching of Free-form Curves
Geometric matching in general is a difficult unsolved problem in computer vision. Fortunately, in many practical applications, some a priori knowledge exists which considerably simplifies the problem. In visual navigation, for example, the motion between successive positions is usually either small or approximately known, but a more precise registration is required for environment modeling. The...

متن کاملDynamic Evaluation of Free-Form Curves and Surfaces
Free-form curves and surfaces represented by control points together with well-defined basis functions are widely used in computer aided geometric design. Efficient evaluation of points and derivatives of free-form curves and surfaces plays an important role in interactive rendering or CNC machining. In this paper we show that free-form curves with properly defined basis functions are the solut...
متن کاملThe Square-free Sieve and the Rank of Elliptic Curves
Let E be an elliptic curve over ij. A celebrated theorem of Mordell asserts that E(ij) , the (abelian) group of rational points of E, is finitely generated. By the rank of E we mean the rank of E(ij). Thus the rank of E is positive if and only if E possesses an infinity of rational points. Relatively few general qualitative assertions can be made about the rank as E varies. How large can the ra...
