That means to calculate the Hessian matrix of optical flow equation, and the weight of Lucas-Kanade＇s method is defined as the reciprocal of the conditioning number of its Hessian matrix.

然后借用灰度直方图的概念构造方向直方图，提取光流特征，方向直方图由量化光流场来得到，再利用方向直方图构造出一个模板库及其索引序列库。

Experimental results show the recognition rate of the method is 95%for a known expresser and 72% for a novel expresser. Aiming at the shortcomings of optical flow technique,two improved optical flow algorithms are presented.One way is to introduce forward and backword constraint eqution and Hessian matrix of optical flow equation is computed.The well- posedness of each point of local neighbourhood is examined and the weight of Lucas-Kanade's method is defined as the reciprocal of the conditioning number of its Hessian Matrix.

3针对传统光流法的缺点，分别提出了两种不同的改进方法：其一为引入前向-后向光流方程，计算其Hessian矩阵，把Hessian矩阵条件数的倒数作为Lucas-Kanade光流法的加权阵，可有效消除局部邻域中不可靠约束点，同时提高基本约束方程解的稳定性；其二为针对传统光流法只适用于刚体运动的特点，在扩展约束光流方程的基础上引入了div-curl样条函数作为扩展光流约束方程的附加约束条件，给出了一阶和二阶div-curl样条约束下光流的数值解。

She was of great use and comfort to us all, and Lady Lucas has been very kind; she walked here on Wednesday morning to condole with us, and offered her services, or any of her daughters, if they could be of use to us.""

伊丽莎白大声说道：还是让她待在自己家里吧，她也许真是出于一片好意，但是遇到了这样一件不幸的事，谁还乐意见到自己的邻居？

Sometimes, Lucas sounded like a downright couturier.

有时，卢卡斯听上去就象一个彻头彻尾的女服设计师。

Based on the criterion that the volume of estimated parameter's joint confidence region should be minimum, which is a sequential experimental design norm for optimal parameter estimation proposed by Box and Lucas, the observations for the adsorption of n -decane on 5 A molecular sieves were determined sequentially, and it is found that the observations should b.

根据Box和Lucas所提出的使待估参数联合置信域的容积趋于最小的参数估算的序贯实验设计准则，推导得出了正葵烷吸附等温线实验观测点的安排原则，发现对于一元线性模型，实验观测点应安排在可操作区的两端。
