The Stability of Convergence of Curve Evolutions in Vector Fields
Junyan Wang, Kap Luk Chan
Curve evolution is often used to solve computer vision problems. If the curve evolution fails to converge, we would not be able to solve the targeted problem in a lifetime. This pa…

Active Contour with A Tangential Component
Junyan Wang, Kap Luk Chan
Conventional edge-based active contours often require the normal component of an edge indicator function on the optimal contours to approximate zero, while the tangential component…
