A Fast Method for NCC Algorithm in Image Matching
Chen Yang · Informatization Research · 2011
In the field of computer vision,image matching is a common task,and point matching based on gray scale is a common method.Among the methods,NCC algorithm with high anti-noise ability and precision is usually used.However,with great computing quantity,NCC algorithm often cannot meet the requirement of real-time processing.In this paper,appropriate matrix with all the elements being ones is introduced.We let it correlate with part of the original image.So the computing quantity of NCC is rapidly reduced and the efficiency is increased.The simulation experiment results also demonstrate the validity of the method presented in this paper.
