Abstract

The invention discloses a fast image matching method based on whale optimization algorithm and gray relational analysis, uses gray relational analysis to simplify the similarity measurement calculation, and then uses whale optimization algorithm to perform matching search to obtain the best matching position, and proposes a noise resistance Better fast image matching algorithm. The invention applies the improved whale optimization algorithm based on gray relational analysis to image matching, realizes fast image matching, makes the image matching algorithm have good efficiency and matching accuracy and good anti-noise performance, and is a practical application value new method.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a fast image matching method based on a whale optimization algorithm and gray relational analysis. Background technique [0002] Image matching is one of the important contents of image processing. The process of image matching actually refers to the process of seeking the mapping between two images. At present, there are two main types of image matching methods: one is the matching method based on grayscale correlation, which directly uses the grayscale of the image for matching, the algorithm is simple, the matching rate is high but the calculation is heavy; the other is based on image features. method, it is necessary to extract features from the image first, and its calculation amount is relatively small, and it has good adaptability to grayscale changes, deformation and occlusion, but the matching accuracy is not high. The pursuit of matching accuracy, ...
