Problems solved by technology

After analysis, it can be seen that there are some obvious flaws in this annotation generation process: on the one hand, manually annotating a large image set is a very time-consuming task; on the other hand, since images from the same subject are similar in content , and the annotations provided by users are not completely related to the image content, and the order of annotations is not necessarily consistent with the importance of image information

Embodiment Construction

[0047] Attached below figure 1 The technical scheme of the present invention is described in further detail:

[0048] The following examples are implemented on the premise of the technical solutions of the present invention, and detailed implementation methods and processes are given, but the protection scope of the present invention is not limited to the following examples.

[0049] In order to effectively label the same subject image, a kind of image automatic labeling method proposed by the present invention is divided into the following three steps: the first step is to select some representative images from the photo collection to describe this type of visual information, which can greatly reduce the The number of training images; the second step, according to the consistency principle of visual information and semantic annotation, reasonably label representative images, which helps to improve the performance of image retrieval and management; finally, using the random wa...

Abstract

The invention discloses an image automatic marking method. The method comprises the following three steps of: selecting some representative images from a personal photo gallery through an affinity propagation clustering algorithm to describe cluster visual information, so that the training image number can be greatly reduced; reasonably marking the representative images according to the visual information and a semantic annotation consistency principle, so that the image searching and managing performance can be improved; and automatically marking the other images through a random walk algorithm with a restarting function.

Description

technical field [0001] The invention relates to an image tagging method in the field of computer technology, in particular to an automatic image tagging method realized by using a random walk algorithm with restart by utilizing the consistency principle of visual information and semantic tagging. Background technique [0002] With the rapid development of the Internet and the high popularity of digital cameras, the number of uploaded images in social media sharing sites such as Flickr, YouTube, and Zooomr has grown exponentially. There are more than 2 million personal photos and 8.5 million registered users on the Flickr website, and these users can mark images of interest at any time. Although image annotation is currently done manually, the annotation often contains information irrelevant to the content, which makes the quality of annotation unsatisfactory. Many annotations provided by Flickr users are imprecise in meaning. According to statistics, only about 50% of the ...
