中文摘要：

提出了一种新颖的活动轮廓模型。该模型有效地利用了测地线活动轮廓（Geodesic active contour,GAC）模型的光滑性和局部区域型 CV（Local Region-based Chan-Vese Model,LRCV）模型的局部区域性。实验结果表明,该模型具有分割精度高、对初始轮廓不敏感等优点。

英文摘要：

A novel active contour method for image segmentation is given out,which utilizes the advantages of the GAC （Geodesic active contour）and the LRCV （Local Region-based Chan-Vese Model）methods.We consider the smoothing force of the GAC method and local region-based force of the LRCV method.Experimental results show that the model can effectively segment the intensity inhomogeneous images while it is robust to the initial contour.
