摘要：One classic algorithm used in template matching is normalized cross correlation method. It often achieves high precision. But it does not meet speed requirements for time-critical applications. To solve that issue, a speed-up way of template matching is proposed. The fast matching way bases on pyramid hierarchical searching algorithm. It adopts two template matching methods to match images, which base on rough matching proceeds local matching precision. Firstly, the coarse matching is performed based on gray-scale projection algorithm. Secondly, the precise matching is made based on several small block matching. The new way is compared to conventional approach without pyramid hierarchical searching by experiments. Experimental result demonstrates that the proposed way efficiently improves the speed of template matching and the precision is unchanged. © (2013) Trans Tech Publications, Switzerland.
