Embodiment Construction

[0107]The embodiment of the present application provides an image retrieval method and a related device, which can be applied to a system or program including an image retrieval function in a terminal device, by obtaining the image features corresponding to the training images in the image database and the training The text features corresponding to the text, wherein the image features include image overall features and image area features, and text features include text overall features and text word features; then determine the global similarity feature based on the image overall features and text overall features; and based on the image area features and The text word feature determines the local similarity feature; then constructs a similarity node according to the global similarity feature and the local similarity feature to transfer similarity information between similarity nodes, wherein the similarity information is used to update the similarity node, The similarity nod...

Abstract

The invention discloses an image retrieval method and a related device, which can be applied to an artificial intelligence computer vision technology. The method comprises the following steps of acquiring image features and text features; then constructing similarity nodes so as to transmit similarity information between similarity nodes; further filtering the similarity nodes according to the weight information; and determining a target similarity value based on the updated similarity node and the filtered similarity node so as to determine a corresponding text retrieval result in response tothe input of the target image. Therefore, a cross-modal information retrieval process is realized, and due to similarity information transmission between the global similarity features and the localsimilarity features and semantic weight screening in the retrieval process, the accuracy of the similarity features is improved, so that the image retrieval accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an image retrieval method and related devices. Background technique [0002] With the rise of the Internet and the explosive presentation of data, massive amounts of information have poured into people's lives. How to use multimedia data to find the data information needed by individuals, not just in text form, is an urgent problem to be solved. Image files, video files, audio files, etc. will become more and more frequent query objects of users. Among them, with the paperless office and multimedia search engine objects, image text processing and retrieval will become an important technology of information retrieval. [0003] Generally, the similarity of global features can be used for image text retrieval, that is, the objects with high similarity of global features are selected as the retrieval results. [0004] However, since there may be text information wi...
