Fat Arcs for Implicitly Defined Curves

We present an algorithm generating a collection of fat arcs which bound the zero set of a given bivariate polynomial in Bernstein– Bézier representation. We demonstrate the performance of the algorithm (in particular the convergence rate) and we apply the results to the computation of intersection curves between implicitly defined algebraic surfaces and rational parametric surfaces.

Robust Computation of Foot Points on Implicitly Defined Curves

We introduce a new method for computing the foot point of a given point on an implicitly defined curve and compare it with existing local and global methods. As demonstrated in this paper, the implicit representation of curves and surfaces is useful not only for solving intersection problems, but also for foot point computation. §

Fitting Implicitly Defined Curves to Unorganized Points with Sharp Features

In order to represent and reconstruct sharp features (i.e., corners) by an implicitly defined curve, we add so–called corner detector functions, which are special radial basis functions, to the function defining the initial curve. The parameters controlling them are automatically adjusted by applying an evolution process.

An Evolution-Based Approach for Approximate Parameterization of Implicitly Defined Curves by Polynomial Parametric Spline Curves

We propose a novel approach for the approximate parameterization of an implicitly defined curve in the plane by polynomial parametric spline curves. The method generates the parameterization of the curve (which may consist of several open and closed branches) without using any a priori information about its topology. If needed the topology of the approximate parameterization can be certified ag...

Implicitly Defined Baseball Statistics

Major League Baseball uses statistics to determine awards every season. The batting champion is given to the player with the highest batting average. The Cy Young Award is given to the top pitcher which is determined by many different statistics including earned run average (ERA). Batting average and ERA have been used for many years and are major statistics in baseball. Neither batting average...
