Abstract

Abstract: A method based on combining active contour with passive edge detection to extract contour is proposed.This method avoids the shortcomings which exist in active and passive techniques，and combines their advantages.To get a better contour，three techniques are used successively，first Canny detector，then segmentation based on probability，and finally snake model.

Key words: Snake model, active contour, Canny detector, probability, image segmentation

摘要： 基于主动轮廓识别和被动轮廓识别方法各自的优缺点，提出结合主动和被动的方法，先对图像进行被动轮廓的预处理，然后再应用主动轮廓的方法，通过比较选出Canny算子进行预处理，再通过基于概率的方法分割图像，最后再应用Snake模型进行轮廓提取。并取得较好的应用。

关键词: Snake模型, 主动轮廓线, Canny算子, 概率, 图像分割
