与C-V模型不同，LBF模型引入了一个以高斯函数为核函数的局部二值拟合（localbinaryfitting，LBF）能量。

LBF models often fail to correct the non-uniform object segmentation to the side of the contour curve , when the initial level set curve is away from the object or cross the border .

当初始水平集曲线远离目标边界或者与目标边界发生交叉时，LBF模型往往不能正确的把非均匀目标分割到活动轮廓曲线一侧。

Because the LBF energy enables the extraction of accurate local image information , LBF model can address the segmentation of images with intensity inhomogeneity , to which C-V models are not applicable .

因为LBF能量能够获取图像的局部信息，所以LBF模型解决了PC模型不能处理灰度不均一图像的分割问题。

When calculating routing table , the routing metric is composed of LCF , LBF and path hop , thus the routing protocol could support Quality of service ( Qos ) and realize load balance .

在计算路由表的时候，LCF、LBF与路径跳数一起构成路由判据，使得路由协议能够提供一定的Qos支持，达到负载均衡的目的。

But there are still many drawbacks needed to be improved . The CV Model is one of the most famous region-based methods . The LBF ( Local Binary Fitting ) model is an improvement of it .

但是，仍然还有许多地方需要进一步完善。CV模型是其中一个著名的基于区域的几何活动轮廓模型，LBF模型为其最新的一个改进。

水火弯曲成形和激光弯曲成形均存在一定局限性，而等离子体弧具有平均能量转换效率高、成本较低等优点。

Output of these engines is commonly rated at105 hp ( 78 kW ) at4800 rpm and137 ft · lbf ( 185 N · m ) at2800 rpm .

这些发动机的输出通常是额定105马力（78千瓦）在4800转和137英尺磅（185牛顿米）在2800转。

The algorithm can not only inherit the merit of GBF which produces fewer expanding nodes , but also dramatically reduce the space cost of GBF and the ineffectiveness of the LBF scheme and , in particular , the depth first scheme .

这一混合算法保持了GBF扩展结点数少的优点，并有效地降低了GBF算法的空间开销，改善了LBF策略特别是深度优先搜索的盲目性。
