Problems solved by technology

[0003] The ABIR method is to use keywords related to the image content to annotate the text of the image. Although better annotation can greatly improve the accuracy of image retrieval, this method has great defects: manual annotation is time-consuming and subjectivity. Too strong, and the image content is difficult to accurately describe with a few keywords, the ABIR method cannot be applied to big data retrieval

Abstract

The invention discloses an image retrieval method and a system based on image segmentation and fuzzy pattern recognition, comprising the following steps: image segmentation: a query image is segmentedinto a plurality of image regions, and each retrieved image is also segmented into a plurality of image regions; feature extraction: extracting comprehensive feature vectors of each image region of the query image; extracting an integrated feature vector for each image region of each retrieved image; obtaining k nearest neighbor images of the query image; obtaining k nearest neighbor images of each retrieved image; for the k nearest neighbor images of the query image and the corresponding k nearest neighbor images of each retrieved image, the similarity of the k nearest neighbor images is calculated, and the similarity of the k nearest neighbor images is weighted and summed to obtain the final similarity between the query images and each retrieved image, and the final similarity is sortedin the order from large to small, and the retrieved images are outputted in the order from large to small.

Description

technical field [0001] The invention relates to an image retrieval method and system based on image segmentation and fuzzy pattern recognition. Background technique [0002] With the rapid development of computer network, multimedia technology and communication technology, digital image data is increasing day by day. How to quickly and accurately query images that people are interested in from massive image data has always been a research hotspot in the field of image retrieval. Generally, image retrieval methods can be divided into two types: annotation-based image retrieval (ABIR) methods and content-based image retrieval (CBIR) methods. [0003] The ABIR method is to use keywords related to the image content to annotate the text of the image. Although better annotation can greatly improve the accuracy of image retrieval, this method has great defects: manual annotation is time-consuming and subjectivity. It is too strong, and the image content is difficult to accurately ...
