利用光流预测Snakes模型初期轮廓的动态图象轮廓追迹方法
摘 要
针对应用Snakes模型进行动态图象轮廓追迹时,若存在前后帧目标变形较大,则易发生追迹失误的问题,提出了利用光流预测Snakes模型的初期轮廓,然后进行动态图象轮廓追迹的方法.实验证明,改进后的方法与原来Snakes模型相比,具有更好的轮廓动态跟踪能力.

Contour Extraction Method of Active Image Using Snakes Model and Optical Flow
() Abstract
In order to extract the contour of active image effectively, this paper gives a method using Snkaes model, while initial contour of every frame is predicted by optical flow. With this improved method, Snkaes model has better performance for contour extraction of active image. Finally, the given algorithm is tested on several images. Comparison is made with standard Snkaes method.
