摘要: 提出了一种基于活动轮廓模型的胃窦B超序列图象边缘轮廓的提取与跟踪方法。对于序列中的第一幅图象,通过人工取人,B样条拟合的方法,提取其初始轮廓,再运用活动轮廓模型,进行边缘轮廓的逼近,以获得比较精确的胃窦边缘轮廓。在后续图象处理中,将活动轮廓模型与光流模型相结合,实现了轮廓的跟踪。实验的结果证明了该方法的有效性。

Abstract: An extraction and tracking of the contour of gastric anthem in the ultrasound sequence images based on active contour models is presented in this paper. To the first image, we get the raw contour by mark some point by person then continue them use B-spline. On this base, we use active contour models to make the rough contour approach the real contour. To the other images, we combine active contour models with light-flow model, reallize the track of the contour. Experimental results proved the validity of our method.
