LBF(Local binary fitting)是在CV模型的基础上发展起来的一种局部化的图像分割模型。分割对象是亮度非均匀图像。缺点：初始位置较为敏感，运算复杂度高。-LBF (Local binary fitting) in the CV model is developed on the basis of a localized Image. Split object is non-uniform image brightness. Disadvantages: initial position is more sensitive to high computational complexity.
