Conformal Snake algorithm for contour detection
Sharon Lam, C.S. Tong · Electronics Letters · 2002
A novel and effective modification of the original Snake algorithm is proposed. The modification can improve the capability of the algorithm to detect boundaries with sharp corners or concave parts without the need to introduce external forces. The essential idea is to apply conformal mapping to transform the image so that the object boundary in the new domain can be captured by the Snake algorithm.
