Algorithm of Video Object Contour Tracking
Deyun Xiao · Jisuanji gongcheng · 2007
A robust and novel method for video object contour tracking by improving the dual-front active contour model.is presented With the metho,the speed of the algorithm is increased greatly by support region restriction,and the adopted quasi-balloon force can both solve the convergence problem results from support region restriction and make tracking more flexible.The method can be adapted to track objects with abrupt speed change and large degree of deformation.It is fast and topology change adaptive.And it can be used even the background is dynamic.Experiments demonstrate its effectiveness and robustness.
