Fast and accurate snake modelfor object contour detection
Wen‐Nung Lie, Cheng‐Hung Chuang · Electronics Letters · 2001
A new scheme in which a snake model is used for object contour detection is proposed. By developing a no-search movement scheme, accepting the effective gradient vector flow field as the contracting force, and adjusting the weighting parameters automatically, an algorithm that is fast, less sensitive to initial contour conditions and accurate in approaching concave parts of an object boundary is obtained.
