| 摘 要： | 针对肝癌CT图像特点,提出了一种改进的B样条曲线的Snake模型图像分割算法,该算法首先对腹部CT图像进行预处理,获得肝脏癌变部分的初始轮廓,再构造闭合B样条Snake模型,最后使用MMSE最小化外力变形模型以实现图像的准确分割。实验结果表明,该方法对于肝癌CT图像取得了肝脏癌变部分目标的良好分割效果。

| Abstract: | An improved B-spline Snake model for image segmentation was proposed,in view of the features of liver cancer CT images.Firstly the abdominal CT imge was preprocessed to obtain liver cancer part of the initial outline,then closed B-spline Snake model was constructed.Finally,deformed model was used for accurate segmentation of image using the MMSE to minisize external force.Exerimental results show that this algorithm was an effective method for segmenting the interested target of liver CT images. |
