摘要: 本文对于模板匹配中的失配度量作了统计分析,确定了失配度量剖面曲线在正确配准点 附近的变化上限,提出了模板匹配的自适应搜索法,导出了所需的阈值公式.对于实际图象的 匹配实验结果,证实了方法的正确性和搜索的快速性,为某些在线应用提供了快速的匹配方 法.Abstract: In this paper, a statistic analysis of mismatch measure in template matching is performed. The upper limit of variation in the neighbourhood of correct registration point for the profile curve of mismatch measure is determined. The adaptive search method of template matching is presented. The required threshold formulas are derived. The validity of the method and the fastness of the search are verified by the results concerning the matching experiment of actual images. The fast matching method .is provided for some on-line applications.
