摘要 本文研究了活动轮廓模型初始化的问题.利用EM算法和小波多尺度边缘检测的方法,获得了活动轮廓模型的外部能量函数和初始曲线,并对于具体的X射线图像给出了实验结果和该算法的有效性. This paper considers the initialization problem of active contour model.By using EM algorithm and wavelet multiscale edge detection,we get the external energy function and the initial curve of active contour model.The paper also showed the experimental results for X-ray image and the effectiveness of method.
