Problems solved by technology

In this context, the traditional text search methods can no longer meet people's special needs, so cross-media retrieval is proposed, and the correlation between different modalities in cross-media retrieval has also attracted more and more attention.
[0004] However, the inventors discovered during the research and development process that most retrieval methods, such as text retrieval, image retrieval, and video retrieval, etc., mostly focus on single-modal retrieval, and can only provide queries and retrievals of the same modality.

Abstract

The invention discloses a cross-modal data retrieval method and system based on graph regularization and modal independence, and the method comprises the steps of receiving the original data of different modalities, carrying out the feature extraction, building a multi-modal data set which consists of the image text pairs in one-to-one correspondence, wherein the multi-modal data set comprises a training set and a test set; projecting the feature matrixes of different modal data in the training set to a public subspace through optimizing a predefined objective function to obtain an image projection matrix and a text projection matrix; according to the image projection matrix and the text projection matrix, projecting the feature matrixes of different modal data in the test set to a publicsubspace; calculating the similarity between the projected matrix and other projection matrixes in the public subspace; and performing descending sort according to the similarity to obtain the data corresponding to the plurality of first feature projection matrixes, and performing the cross-mode retrieval.

Description

technical field [0001] The disclosure belongs to the technical field of data retrieval, and relates to a cross-modal data retrieval method and system based on graph regularization and modality independence. Background technique [0002] The statements in this section merely provide background technical information related to the present disclosure and do not necessarily constitute online technology. [0003] In the era of big data with the rapid growth of multimedia information, the types of media information have developed from the original text to images, texts, and videos; the ways of obtaining information have also evolved from broadcasting and newspapers to websites, Weibo, WeChat, and QQ. In this context, the traditional text search methods can no longer meet people's special needs, so cross-media retrieval is proposed, and the correlation between different modalities in cross-media retrieval has attracted more and more attention. [0004] However, the inventors disco...
