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。
A method based on combining active contour with passive edge detection to extract contour is proposed.This meihod 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.
