Abstract: This paper presents a novel method of image matching based on gray value weighting NMI, which combines the advantages of gray matching and feature matching, and defines the concept of gray weighting, which not only enhances the feature extraction quality of NMI, but also reduces the amount of correlative computation during gray matching. All these improve the matching quality and matching speed.

Key words: correlation computation, image matching, image processing
