Abstract

The present invention relates to the field of computer image retrieval, and proposes a similar image matching method based on a fuzzy weighted histogram, comprising the following steps: S1, respectively computing and processing the query image and the image to be retrieved, and obtaining the fuzzy weighted feature histogram of the query image and the fuzzy weighted feature histogram of each image to be retrieved; S2, calculate the feature similarity value between the query image and the weighted feature histogram of each image to be retrieved, obtain a set of feature similarity values, and perform positive processing according to the feature similarity value Sorting to establish a similar image index table; S3. According to the displayed number of similar matching images, retrieve similar matching images satisfying the conditions from the similar image index table and display them. The invention improves the matching accuracy of similar images and can be widely used in the field of image retrieval.

Description

technical field [0001] The invention relates to the field of computer image retrieval, in particular to a similar image matching system and method based on a fuzzy weighted histogram. Background technique [0002] Similar image matching is to match a given query image in the image database with an image that is semantically similar to the query image, which is a classic problem in image retrieval in the field of computer vision. With the rapid development of Internet and image processing technology, the practical application value of similar image matching system is increasing day by day. [0003] The representation of visual features of images is the key technology to match similar images and accurately return the results. By improving the representation performance of visual features, the semantic interpretation of image content can be better obtained, so that images can be better distinguished sexual characteristics. The image matching method can accurately return the m...
