Detection of video sequences using compact signatures

J. Zobel
2006 ACM Transactions on Information Systems  
We propose four new methods for producing compact video signatures, based on the way in which the video changes over time.  ...  These methods are much faster than previously proposed techniques; using a more compact signature, this query can be completed in a few milliseconds.  ...  Each of these use different properties of the video to produce compact signatures. The most compact signature-the shot-length signature-is based on the pattern of edits in the video.  ...

A suffix array approach to video copy detection in video sharing social networks

Ping-Hao Wu, Tanaphol Thaipanich, C.-C. Jay Kuo
2009 2009 IEEE International Conference on Acoustics, Speech and Signal Processing  
Specifically, we develop a compact one-dimensional signature based on the shot change position of video files.  ...  Unlike images and audio, the size of a video file is usually large, which makes it computationally expensive to match two long signature sequences.  ...  The rest of the paper is organized as follows. We present a compact video signature by examining the temporal variation of a video in Sec. 2.  ...

Scalable mining of large video databases using copy detection

Sébastien Poullot, Michel Crucianu, Olivier Buisson
2008 Proceeding of the 16th ACM international conference on Multimedia - MM '08  
Many valuable links between video segments can be identified by content-based copy detection methods, where "copies" are transformed versions of original video sequences.  ...  To make this approach viable for large video databases, we put forward a new mining method relying on the definition of a compact keyframe-level descriptor and of a specific index structure.  ...  The video sequence descriptors are very compact, so relatively large video databases can be processed, but the application of these solutions is limited to rather specific video content.  ...

Video Clip Matching Using MPEG-7 Descriptors and Edit Distance [chapter]

Marco Bertini, Alberto Del Bimbo, Walter Nunziati
2006 Lecture Notes in Computer Science  
Video databases require that clips are represented in a compact and discriminative way, in order to perform efficient matching and retrieval of documents of interest.  ...  We present a method to obtain a video representation suitable for this task, and show how to use this representation in a matching scheme.  ...  This work also proposed the use of inverted indices to detect copies of a video clip. In [3] , audio features were also used as part of the signature.  ...
