Emerging Internet services and applications attract increasing users to involve in diverse video-related activities, such as video searching, video downloading, video sharing and so on. As normal operations, they lead to an explosive growth of online video volume, and inevitably give rise to the massive near-duplicate contents. Near-duplicate video retrieval (NDVR) has always been a hot topic. The primary purpose of this paper is to present a comprehensive survey and an updated review of the advance on large-scale NDVR to supply guidance for researchers. Specifically, we summarize and compare the definitions of near-duplicate videos (NDVs) in the literature, analyze the relationship between NDVR and its related research topics theoretically, describe its generic framework in detail, investigate the existing state-of-the-art NDVR systems. Finally, we present the development trends and research directions of this topic.

大规模近重复视频检索研究进展

新兴的Internet服务和应用吸引了越来越多的用户参与与视频相关的各种活动，例如视频搜索，视频下载，视频共享等。作为正常的运营方式，它们导致在线视频量的爆炸性增长，并且不可避免地会产生大量近乎重复的内容。几乎重复的视频检索（NDVR）一直是热门话题。本文的主要目的是对大规模NDVR的进展进行全面的调查和更新，以为研究人员提供指导。具体来说，我们总结并比较文献中的近复制视频（NDV）的定义，从理论上分析NDVR及其相关研究主题之间的关系，详细描述其通用框架，研究现有的最新NDVR系统。最后，
