摘要
传统图象匹配算法利用相关法进行逐点计算,计算量大且做了许多无用功。该文提出一种利用图象灰度局部特征的约束,首先对图象进行粗匹配找出可能出现的区域,再进行精确匹配来定位,该方法计算量小,从而提高搜索效率。
Normalized pattern matching is based on correlation and operated point by point with a large quantum of operation and low efficiency.This paper gives a kind of restriction using local character of image grayscale.First a general matching will find the possible appearing area of image,then an accurate matching will locate it.The quantum of this kind of operation is very small,thus improves the efficiency of search..
