Snakes模型的改进算法

讨论了Snake模型的一种新型改进模型即基于矢量场卷积的模型,作为GVF模型的一般形式,该卷积模型适用范围普遍性,比传统模型具有更好的鲁棒性。通过对比Snakes经典、传统模型,并在轮廓、噪声敏感度、算法复杂度方面做分析和验证,实验结果表明,VFC对噪声、初始轮廓敏感性要求不高,而在算法时间上有较大的提升。

An Overview on the Improved Algorithm of the Snakes Model

This article discusses an improved model of the Snake model,which is based on the vector field convolution model.This model serves as the general form for the GVF model.The convolution model is applicable to a wider range and has better robustness than the traditional model.By comparing the classic and traditional Snakes models and analyzing the contours,noise sensitivity and complexity of the algorithm,it is shown that VFC does not have a high requirement on noise and initial contour sensitivity and that its design remains to be improved.
