Efficient Storage Support for Real-Time Near-Duplicate Video Retrieval [chapter]

Zhenhua Nie, Yu Hua, Dan Feng, Qiuyu Li, Yuanyuan Sun
2014 Lecture Notes in Computer Science  
Near-duplicate video retrieval in a real-time manner is important to offer efficient storage services, and becomes more challenging due to dealing with the rapid growth of multimedia videos.  ...  The idea behind FastVR is to leverage space-efficient indexing structure and compact feature representation to facilitate keyframe based matching.  ...  These retrieval methods mainly address the exact-matching query in the metadata search, rather than the near-duplicate retrieval for videos in a real-time manner.  ...

Fast tracking of near-duplicate keyframes in broadcast domain with transitivity propagation

Chong-Wah Ngo, Wan-Lei Zhao, Yu-Gang Jiang
2006 Proceedings of the 14th annual ACM international conference on Multimedia - MULTIMEDIA '06  
This paper explores the symmetric and transitive nature of near-duplicate for the effective detection and fast tracking of NDK pairs based upon the matching of local keypoints in frames.  ...  The identification of near-duplicate keyframe (NDK) pairs is a useful task for a variety of applications such as news story threading and content-based video search.  ...  The symmetric property states that if a keyframe k1 is a near-duplicate of k2, it implies that k2 is also a near-duplicate of k1.  ...

Scalable detection of partial near-duplicate videos by visual-temporal consistency

Hung-Khoon Tan, Chong-Wah Ngo, Richard Hong, Tat-Seng Chua
2009 Proceedings of the seventeen ACM international conference on Multimedia - MM '09  
Most existing techniques either focus on the fast retrieval of full copies or near-duplicates, or consider localization in a heuristic manner.  ...  To precisely decide the boundaries of the overlapping segments, pair-wise constraints generated from keypoint matching can be added to the network to iteratively refine the localization result.  ...  To evaluate the performance of TNP, we compare it with two state-of-the-art methods for near-duplicate video retrieval.  ...

Practical elimination of near-duplicates from web video search

Xiao Wu, Alexander G. Hauptmann, Chong-Wah Ngo
2007 Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07  
A search on typical popular video often returns many duplicate and near-duplicate videos in the top results.  ...  Only when a video cannot be clearly classified as novel or nearduplicate using global signatures, we apply a more expensive local feature based near-duplicate detection which provides very accurate duplicate  ...  keypoints for detecting near-duplicate web videos.  ...
