Variance components estimated by MINQUE method can be used in significance test for linear contrasts of variety effects.
用MINQUE法估算各项方差分量，然后对品种效应的线性对比作显著性测验。
The proposed method is divided into two steps: 1 license plate location by the variance of gray image, and 2 license plate segmentation by connected components analysis and projection analysis.
该系统由两个重要步骤组成：1基于灰度方差的车牌定位算法，2结合连通域分析和投影分析的字符切分算法。
