中文摘要：

缩小图像低层视觉特征与高层语义之间的鸿沟,以提高图像语义自动标注的精度,进而快速满足用户检索图像的需求,一直是图像语义自动标注研究的关键.粒度分析方法是一种层次的、重要的数据分析方法,为复杂问题的求解提供了新的思路.图像理解与分析的粒度不同,图像语义标注的精度则不同,检索的效率及准确度也就不同.本文对目前图像语义自动标注模型的方法进行综述和分析,阐述了粒度分析方法的思想、模型及其在图像语义标注过程中的应用,探索了以粒度分析为基础的图像语义自动标注方法并给出进一步的研究方向.

英文摘要：

To bridge the semantic gap between low-level visual feature and high-level semantic concepts has been the subject of intensive investigation for years in order to improve the accuracy of automatic image annotation and satisfy the users needs of quick image retrieval.Granular analysis is a hierarchical and important data analyzing method,which provides a new idea and method for solving the complicated problem.The accuracy of automatic image annotation and the efficiency of image retrieval are varying with the granularity size of image understanding and analysis.In this paper,the state-of-art models of automatic semantic image annotation are overviewed,then the idea and models of the granular analysis with its application in the process of automatic semantic image annotation are discussed,and the granular analysis based automatic image annotation methods are investigated as well as the promising research directions are given.
