While matching, only the principal component directions corresponding to the rows of the same serial numbers in searching area are needed to be extracted for the computation of projection value so as to form the vectors of projection values. The distances between MM-vectors and the vectors formed by projection values are computed, and whether the two kinds of vectors are matchable should be in accordance to those distances.

在匹配时，只需抽取搜索区域中相同序号的列向相应的主元方向作投影运算，从而构成投影值向量，进而计算该向量与预处理中所得的最大最小值构成向量间的距离，从而根据距离的大小判断是否匹配。
