A concept for parametric surface fitting which avoids the parametrization problem
An active contour model to surface approximation is presented. It adapts to the model shape to be approximated with help of local quadratic approximants of the squared distance function. The approach completely avoids the parametrization problem. The concept is open for inclusion of smoothing operators and shape constraints. (C) 2003 Elsevier B.V. All rights reserved.
