FXPAL Interactive Search Experiments for TRECVID 2007

John Adcock, Jeremy Pickens, Matthew Cooper, Lisa Anthony, Francine Chen, Pernilla Qvarfordt
2007 TREC Video Retrieval Evaluation  
In 2007 FXPAL submitted results for two tasks: rushes summarization and interactive search. The rushes summarization task has been described at the ACM Multimedia workshop [1] .  ...  The other submitted runs (FXPAL CO*) employed a novel real-time, multi-user, collaborative search system.  ...  We have yet to perform statistical significance analysis on these results but similarly small differences in 2005 proved to have a very high level of statistical significance.  ...

Efficient targeted search using a focus and context video browser

Ork De Rooij, Marcel Worring
2012 ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)  
Examples from recent TRECVID benchmarks include the Informedia Storyboard interface [Christel and Yan 2007] and the FXPal MediaMagic [Adcock et al. 2007 ], which use a recognizable grid layout to browse  ...  In literature, and at benchmarks like TRECVID, we see a variety of systems, each with unique approaches to interactive search.  ...

Scenario based dynamic video abstractions using graph matching

JeongKyu Lee, JungHwan Oh, Sae Hwang
2005 Proceedings of the 13th annual ACM international conference on Multimedia - MULTIMEDIA '05  
In order to evaluate the effectiveness of the proposed SBD using graph matching (GM-SBD), we compare it with the SBD proposed by FXPAL Lab (FX-PAL) [1] , which has one of the best methods in TRECVID 2004  ...  In case of gradual changes, GM-SBD is more accurate than FXPAL.  ...

Beyond actions: Exploring the discovery of tactics from user logs

Jiyin He, Pernilla Qvarfordt, Martin Halvey, Gene Golovchinsky
2016 Information Processing & Management  
In addition, as the resulting analysis is at a tactical level we reduce potential issues surrounding the need for interpretation of low-level user actions for log analysis.  ...  Alternatively, in lab studies user activities can be analysed at a higher level, such as search tactics and strategies, abstracted away from detailed interface implementation.  ...  He was instrumental for this work by bringing all of us together during a few months at FXPAL, where the foundation of this research project was laid.  ...

Multimodal Indexing of Presentation Videos

Michele Merler
This work aims at recognizing visual content "in the wild", where the system cannot rely on any additional information besides the video itself.  ...  Recently researchers at FXPAL have introduced Talkminer [Adcock et al., 2010] , which is the first large scale fully automatic presentation video indexing system.  ...  I want to thank Yu-Gang Jiang and Yadong Mu for the great help and collaboration on the Trecvid MED tasks.  ...
