The polynomial function bases are used to form the approximately matching function. Moreover, the discrete values of grey image is transformed to polinomial function that are exact fit at the considered pixel locations. As a result, The mathematical operations performed such as derivation, integration, and gradient evaluation also give out the polynomial functions, therefore, the system of undetermined coefficient equations is derived to be a system of linear algebraic equations.

我们把立体匹配过程看作泛函的极小化过程，因此选用变分问题近似解法的Ritz法构造数值算法，以多项式函数为基构作匹配函数的近似解，进而又利用多项式过样值点的拟合将离散的灰度图象变换为多项式函数，因此计算中所需的求导，积分，及梯度运算的结果仍然是多项式函数，最终将待定系数方程组化为线性代数方程组。

But, such a vectorization will bring three potential problems at least:① Some implicit structural or contextual information may be corrupted;②the higher the dimension of input pattern, the more space are needed for storing weight vector;③When the dimension of pattern is very high and the sample size is small, linear classifier tends to be overstrained.

但如此至少会带来3个不足：①原有矩阵模式的空间或结构信息可能会遭到破坏；②由于权向量的维数等于输入模式的维数，当输入模式维数很大时，权值的存储空间相应地会很大；③对于大维数的模式，当样本数不多时，利用线性分类器易导致过拟合。

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.
