The problem of dismatching concave contours in traditional active contour model is studied, with an analysis of both internal and external energy.
针对传统主动轮廓模型不能有效拟合凹陷轮廓的问题进行研究，从内部、外部能量两方面进行分析。
Second, the locations and contours of polysaccharides are used to initialize VFC. Then the polysaccharides are accurately detected by the active contour model.
其次，利用粗提取得到的多糖分子位置和轮廓来初始化VFC活动轮廓，再进行活动轮廓变形来精确地检测多糖分子。
