中文摘要：

近似拷贝图像检测具有重要实际应用前景,获得了广泛的研究。但当前并没有一篇对已取得的进展进行回顾与分析的近似拷贝图像检测综述论文。通过文献调研分析方法,该文根据特征描述的方式不同将已有方法分为基于全局特征方法和基于局部特征方法,并分别介绍了两类方法的基本框架和主流方法。基于以上分析,总结了两类方法面临的困难及今后的发展方向。

英文摘要：

The research of nearduplicate image detection obtains widely focuses because of its really applica tion prospect. But currently there is not a paper which reviews and analyses the proposed methods by many re searchers. These methods are divided into two categories which are global feature based method and local fea tures based method. This paper also introduced the framework of the two kinds of methods by surveying the ex isting methods. Then it listed the major methods, summarized the difficulties which the two kinds of methods faced, and obtained the future research ideas and directions.
