Level Set方法在轮廓界面追踪问题中的应用

Application of Level Set Method in Tracing the Outline of Interface

运用Level Set方法研究图像轮廓追踪问题。首先,运用差分法检测出图像的初始轮廓线,然后采用基于Level Set方法的偏微分方程数值解理论来进行图像轮廓界面的提取。Matlab实验结果表明,该方法可以测出模糊或离散的边界,得到精确的图像轮廓界面。

This paper study image contour tracing using Level Set Method. First of all, the paper use difference method to detect the initial contour of image, and then extract the contour of image interface with the use of numerical solutions of the partial differential equations based on Level Set method. Matlab experimental results show that this method can detect discrete or fuzzy borders, so as to obtain contours of the image interface.
