Problems solved by technology

[0004] At present, the automatic image annotation technology mainly refers to the annotation of the underlying semantics and entity semantics of images. Based on this, users cannot retrieve images by inputting advanced semantic content.

Embodiment Construction

[0099] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0100] In order to realize the labeling of hot topics on the Internet in images, it is necessary to determine the hot topics on the Internet corresponding to the images. We know that on the Internet, most images are interspersed with text information. We call the text information that appears together with the image as accompanying text, such as the text information in the web page text. Images and accompanying texts are largely related, so we can preliminarily think that the hot topics reflected in these accompanying texts are the hot topics corresponding to the images.

[0101] We know that the semantics of an image can be derived from its similar images. Based on this, the present invention needs to retriev...

Abstract

The invention discloses methods for labeling and searching advanced semantics of images based on network hot topics and a device. The method for labeling the advanced semantics of the images comprises the step of: searching images similar to the entity semantics of images to be labeled and accompanying texts by using an entity semantic work of the images to be labeled based on a search engine of text key words, then extracting topics from the accompanying texts, establishing association relationship among topics, among images, and between images and topics, based on the association relationship, classifying the images with similar topics and visual features into a type, and classifying similar topics corresponding to the images with the similar visual features into a type; and selecting image types which are the most similar to the images to be labeled in the visual features of the images, and taking the corresponding topics as hot topics. According to the invention, by means of the process, the advanced semantic labeling the images is realized, and in addition, the obtained advanced semantics can be used to accurately describe the images to be labeled through denoising.

Description

technical field [0001] The invention relates to the field of image labeling and retrieval, in particular to an image high-level semantic labeling and retrieval method and device based on network hot topics. Background technique [0002] Image is a kind of complex multimedia data, which contains rich semantic content. The semantics of the image is divided into three levels. The first layer is the underlying semantic layer, which uses the underlying visual features such as color and texture extracted from the original image data; the second layer is the entity semantic layer, which uses the extracted underlying visual features to perform Certain logical reasoning, identifying the object category contained in the image, and extracting entity semantics around the object in the image. The third layer is the abstract semantic layer, that is, advanced semantics, which includes advanced semantics such as scenes, behaviors, and emotions, and is a more advanced reasoning of entity se...
