Indexing Large Online Multimedia Repositories Using Semantic Expansion and Visual Analysis
Found in: IEEE MultiMedia
By Xavier Sevillano,Tomas Piatrik,Krishna Chandramouli,Qianni Zhang,Ebroul Izquierdo
Issue Date:July 2012
pp. 53-61
The proposed framework automatically predicts user tags for online videos from their visual features and associated textual metadata, which is semantically expanded using complementary textual resources.
Describing Objects with Multiple Features for Visual Information Retrieval and Annotation
Found in: Image Analysis for Multimedia Interactive Services, International Workshop on
By Qianni Zhang, Ebroul Izquierdo
Issue Date:May 2008
pp. 80-83
This paper describes how a multi-feature merging approach can be applied in semantic-based visual information retrieval and annotation. The goal is to identify the key visual patterns of specific objects from either static images or video frames. It is sho...
Context Inference in Region-Based Image Retrieval
Found in: Semantic Media Adaptation and Personalization, International Workshop on
By Qianni Zhang, Ebroul Izquierdo
Issue Date:December 2007
pp. 187-192
In this paper, a method for inference of high-level semantic information for image annotation and retrieval is proposed. Bayesian theory is used as a tool to model a belief network to configure semantic labels for image regions. These semantic labels for r...
Human action recognition by fast dense trajectories
Found in: Proceedings of the 21st ACM international conference on Multimedia (MM '13)
By Ebroul Ezquierdo, Qianni Zhang, Zongbo Hao, Nan Sang
Issue Date:October 2013
pp. 377-380
In this paper, we propose the fast dense trajectories algorithm for human action recognition. Dense trajectories are robust to fast irregular motions and outperform other state-of-the-art descriptors such as KLT tracker or SIFT descriptors. However, the us...
Enhanced visualisation of dance performance from automatically synchronised multimodal recordings
Found in: Proceedings of the 19th ACM international conference on Multimedia (MM '11)
By Cyril Concolato, Ebroul Izquierdo, Jean Lefeuvre, Marc Gowing, Noel E. O'Connor, Philip Kell, Qianni Zhang, Robin Tournemenne, Slim Essid, Vlado Kitanovski, Xinyu Lin
Issue Date:November 2011
pp. 667-670
The Huawei/3DLife Grand Challenge Dataset provides multimodal recordings of Salsa dancing, consisting of audiovisual streams along with depth maps and inertial measurements. In this paper, we propose a system for augmented reality-based evaluations of Sals...
Towards an expressive virtual tutor: an implementation of a virtual tutor based on an empirical study of non-verbal behaviour
Found in: Proceedings of the 2010 ACM workshop on Surreal media and virtual cloning (SMVC '10)
By Ebroul Izquierdo, Iordanis Biperis, Krishna Chandramouli, Maher Ben Moussa, Nadia Magnenat-Thalmann, Petros Daras, Qianni Zhang, Seyed Navid Haji Mirza, Zerrin Kasap
Issue Date:October 2010
pp. 39-44
In this paper we investigate the non-verbal behaviour of a tutor and propose a model for ECAs (Embodied Conversational Agents) acting as virtual tutors. We have conducted an empirical study where we focused on the distribution of gaze, head and eyebrowns b...
Analysing multimedia content in social networking environments
Found in: Proceedings of the 2010 ACM workshop on Social, adaptive and personalized multimedia interaction and access (SAPMIA '10)
By Charalampos Patrikakis, Ebroul Izquierdo, Naeem Ramzan, Qianni Zhang
Issue Date:October 2010
pp. 73-76
Social and Peer-to-Peer (P2P) networks have received considerable interest in recent decades due to its focus on analysis and relationships among entities and on the patterns and implications of these relationships. In the meantime, with the rapid increase...
Concept based interactive retrieval for social environment
Found in: Proceedings of the 2010 ACM workshop on Social, adaptive and personalized multimedia interaction and access (SAPMIA '10)
By Ebroul Izquierdo, Krishna Chandramouli, Qianni Zhang, Tijana Janjusevic
Issue Date:October 2010
pp. 15-20
Following the recent developments in social networking, there is an emerging interest to share experiences online with social peers through multimedia data. Consequently, exponential amount of multimedia information has been generated by everyday users and...
