摘要

图像语义标注是图像语义分析研究中的一个重要问题.在主题模型的基础上，本文提出一种新颖的跨媒体图像标注方法来进行图像间语义的传播.首先，对训练图像使用主题模型，抽取视觉模态和文本模态信息的潜在语义主题.然后，通过使用一个权重参数来融合两种模态信息的主题分布，从而学习到一种融合主题分布.最后，在融合主题分布的基础上训练一个标注模型来给目标图像赋予合适的语义信息.在标准的MSRC和Corel5K数据集上将提出的方法与最近著名的标注方法进行比较实验.标注性能的详细评价结果表明提出方法的有效性.

Abstract

Image semantic annotation is an important issue in image semantic analysis research.Based on the topic model

this paper proposes a novel cross-media image annotation approach for propagating the semantics among images.First

the topic model is used to capture the latent semantic topics from the visual and textual modal information in the training images.Then

a fused topic distribution is learned by merging the topic distribution of each modality using a weight parameter.Finally

an annotation model based on the fused topic distribution is trained to assign the target images using appropriate semantics.A comparison of the proposed approach with the recent state-of-the-art annotation approaches on the standard MSRC and Corel5K datasets is presented

and a detailed evaluation of the performance shows the validity of our approach.
