Image retrieval system and method for maintaining geometrical shape information of object

Abstract

The invention discloses an image retrieval system and method for maintaining the geometrical shape information of an object. The system comprises an image importing interface, an image retrieval client, a manager interface for receiving system management orders, a system management module for executing manager requests, an image modeling module for abstracting the image as a weighted image, an image frequent pattern mining module for mining vision patterns, an image retrieval module for comparing and matching retrieval items with records and a data storage, access and management service module based on an HBase image database. The geometrical relative position information among various object features can be effectively controlled through the image modeling for maintaining the geometrical information of an object, so that the recall ratio and the precision ratio of the system are greatly increased as compared with those of the traditional model; and the response speed of the system is increased by combining the Bloom filter of HBase and using the frequent subimage index technology, and the system supports the online searching of massive images.

Description

technical field [0001] The invention relates to the field of image retrieval, in particular to an image retrieval system and method for maintaining geometric shape information of objects. Background technique [0002] Image retrieval is usually defined as: using specific retrieval items, such as keywords, voice, images, etc., to search for pictures that meet the requirements of the retrieval items in the existing image database. [0003] At the beginning of information retrieval, image retrieval has attracted a large number of users. The goal of image retrieval is how to quickly return the images that need to be retrieved according to the retrieval items. According to different retrieval items, mainstream image retrieval technologies mainly include keyword-based and image-based image retrieval technologies. [0004] The existing keyword-based image retrieval technologies are relatively mature, mainly including: image retrieval technologies launched by large search sites su...

AI Technical Summary

Problems solved by technology

[0007] The existing image-based image retrieval system mainly has the following deficiencies: A), limited to local feature information, and lacks description of object shape information

For these high-dimensional low-level features, the traditional indexing mechanism is no longer effective, and the performance drops sharply, even worse than sequential scan or exhaustive search, and there is a danger of dimension disaster
