The accuracy and precision of curvature estimation methods
Marcel Worring, Arnold W. M. Smeulders · 2003
Deals with the estimation of curvature from digital image data, especially the selection of a curvature estimation procedure based on its accuracy and precision. The authors establish that almost all curvature estimation techniques from literature suffer from a severe directional inaccuracy and/or poor precision (errors depend on the method, orientation and scale ranging from 1% to more than 200%). A practical solution to the curvature estimation problem is presented.>
