在降低信息冗余度的特征选择处理过程中，首先引用皮尔逊x`准则和偏度一峰度准则检验各特征量的正态性，并对正态分布特征采用参数法而非正态分布特征采用Parzen窗函数法分别估计其类条件概率密度；然后，基于欧氏距离和条件概率的类别可分性判据，分步骤结合单独最优组合法与l-r法这两种次优特征选择方法，在每两类白细胞之间筛选准最优特征组合。
Motion estimation is a uncertainty problem, which can't be actually solved because of discontinuity, data distortion and random noise of an image if we only start with the algorithm of MAP (maximum a posteriori probability).
运动估计问题具有不适定性，单纯采用最大后验概率算法，实际上并未解决运动矢量的不连续、矢量的失真与随机噪声等棘手问题。
