A Dual Active Contour Incorporating Parametric Shape Description
S. Richard Gunn, Mark S. Nixon · ePrints Soton (University of Southampton) · 1994
Active contours are now established as a technique for extracting salient contours from an image. Unfortunately the original technique suffers from many problems. A novel model-based dual active contour, a method of integrating parametric shape information with two active contours, has been developed to overcome the primary problems; sensitivity to initialisation and undesirable attractions by insignificant localised or regionalised features. The robustness of the technique is demonstrated by application to the extraction of a head boundary for face location.
