Aiming at the large computing costs problem for gradient orientation of the image applied in rotation-invariant template matching,this paper proposes an improved rotation-invariant template matching method based on gradient orientation code.It uses integral histogram to reduce the computing costs of computer histograms,and uses pixel-jump method to reduce a lot of ineffective matching operations.Experimental result shows that the method can speed up from 3 to 6 times in the premise of ensuring matching accuracy,so it can meet real-time requirement.
