Improving acoustic speaker verification with visual Body-Language features

Christoph Bregler, George Williams, Sally Rosenthal, Ian McDowall
2009 2009 IEEE International Conference on Acoustics, Speech and Signal Processing  
We show how an SVM based acoustic speaker verification system can be significantly improved in incorporating new visual features that capture the speaker's "Body Language."  ...  With shots that are longer then 5 minutes (i.e. a speech), our shot-detector cuts the video into 5 minute shots. Sometimes we get very short shots of just a few seconds.  ...  Introduction Among the reasons for recent advances in speaker recognition are discriminative classification based on SVMs [10] and novel feature extraction methods, based on both short-term spectral  ...

Group-based spatio-temporal video analysis and abstraction using wavelet parameters

M. Omidyeganeh, S. Ghaemmaghami, S. Shirmohammadi

Automatic analysis of movies for content characterization

Sher Muhammad Doudpota, Sumanta Guha
2010 2010 International Conference on Networking and Information Technology

Cross-Modal Analysis of Audio-Visual Film Montage

Matthias Zeppelzauer, Dalibor Mitrovic, Christian Breiteneder
2011 2011 Proceedings of 20th International Conference on Computer Communications and Networks (ICCCN)  
We propose a cross-modal approach that extracts sequences from a movie with synchronous audio-visual montage. Experiments confirm that the extracted sequences have high semantic relevance.  ...  Consequently, they represent a useful basis for different high-level movie abstraction tasks such as automated movie annotation and movie summarization.  ...  However, we observe that this assumption is not sufficient for the detection of synchronous montage in feature films for two reasons.  ...

Video Summarization: Survey on Event Detection and Summarization in Soccer Videos

Yasmin S., Soudamini Pawar
2015 International Journal of Advanced Computer Science and Applications  
We have discussed some features used for generating video summaries. As soccer is the world's most famous game played and watched, it is taken as a case study.  ...  In such cases, the users may just want to view the summary of the video that is just an abstract of the original video, instead of watching the whole video that provides more information about the occurrence  ...  Compared with static summarization, there are relatively few works being addressed for dynamic video skimming. Most techniques are based mainly on visual information.  ...

2009 Multimedia Content Access: Algorithms and Systems III  
ABSTRACT We present a technique for genre-independent scene-change detection using audio and video features in a discriminative support vector machine (SVM) framework.  ...  We also find that the genres that benefit the most are those with which the previous audio-only was least effective.  ...  The color bhattacharyya feature by itself is substantially better than our previous visual feature based on shot changes, and the combination of shot change, color bhattacharyya, and audio features yields  ...
