| 摘 要： | RSF（Region-Scalable Fitting）模型能够分割灰度不均一图像，但对活动轮廓的初始化和噪声较为敏感。运用理论探究与实验相结合的方法，基于RSF模型，添加一个新的水平集线性正则化项，得到了一个新的活动轮廓模型。实验表明，该模型能够分割灰度不均一图像，对初始轮廓的大小和位置不敏感，抗噪性也较强。

| Abstract: | RSF（Region-Scalable Fitting） model is able to deal with intensity inhomogeneity;however,it is sensitive to initial-ization and noise.Therefore,using the theories probe and experiment,the method of combining,based on RSF model,adding a level set linear regularization item,this paper proposes a novel active contour model.This model can address the segmenta-tion of images with intensity inhomogeneity,while it allows for flexible initialization of the contours and is significantly less sensitive to noise. |
