Others claimed that the Hessian soldier rose from the grave to lead the Hessian soldiers in a charge up nearby Chatterton Hill, not knowing that the hill had already been taken by the British.

另一些人则认为这个黑森士兵还不知道附近的查特顿山已被英国人占领，他从坟墓里出来便是要领导其他黑森士兵向那儿冲锋。

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。
