中文说明：LBF 模型是一个著名的基于区域的活动轮廓模型。与PC（Piecewise Constant）模型不同，该模型引入了一个以高斯函数为 核函数的局部二值拟合（Local Binary Fitting，LBF）能量。因为LBF 能量能够获取图像的局部信息27948194LBF
English Description：
LBF model is based on a well-known active contour model region. And PC (Piecewise Constant) models, this model introduces a local binary Gaussian kernel function fitting (Local Binary Fitting, LBF) energy. Because energy can obtain local information LBF images
