| 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。

| 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. |

| Keywords: | Snake model active contour Canny detector probability image segmentation |
