<p>Described is a method for fitting a parametric representation to digital data. A vector distance field is generated to represent a set of objects and a parametric representation for the set of objects is initialized. A fitting error is determined from the vector distance field representation. The fitting error indicates the accuracy of the fit of the parametric representation to the set of objects. The parametric representation is adjusted and the fitting error is again determined in an iterative manner until an acceptable fitting error is achieved. The method has numerous technical advantages such as robustness, speed, simplicity relative to standard approaches, and the ability to manage constraints such as maintaining corners and enforcing continuity.</p> |
