多值函数

In order to remedy this kind of shortage, this paper presents a quick volume rendering method, for the finite element data field of dam seismic response, choices the slicing direction relying on the element surface which normal line has the smallest included angle with the view direction, slices elements to many quadrilaterals, blends the colors of these quadrilaterals by using OpenGL blending technology, and then superimposes all elements one by one.

为了弥补传统体绘制静止画面不能明确判断场值集中部位的不足，提出一种快速体绘制算法，针对大坝地震反应有限元计算数据场，根据每个单元法线与视线夹角最小的表面来选择剖切方向，将单元剖切成多个四边形面后，对单元的绘制顺序进行合理排序，利用OpenGL图形库函数进行颜色融合，再将各个单元依次叠加，从而生成了三维数据场的体绘制图。

By using middle value of boundary line of water quality grade appraised by traditional biological indexes evaluation as datum point to from the functions of membership, the rationaliza.

通过选取传统生物指数评价结果分级界线的中值作为基准点构造隶属函数，提高了生物指数评价方法的精确性和合理性，提出了多项生物指数模糊评价的基本方法，并在浑江水库的水质评价中取得了较好的应用效果。

Firstly, the maximum likelihood criterion is employed to model the multi-view tracking problem. Then, the likelihood function is factorized based on the conditional independent assumptions. Finally, the estimation of the target location in each camera view is obtained by using an efficient message passing mechanism. In our algorithm, image data from all cameras no longer need to be transmitted to and processed by a central unit.

该算法首先利用最大似然准则对多视角目标跟踪问题进行建模，并对似然函数进行分解，最后借助消息传递机制高效求解出跟踪目标在各个摄像机视野中位置的估计值，而不再需要将图像数据传输到中央处理单元进行集中式处理。
