Summarizing raw video material using Hidden Markov Models
Found in: Image Analysis for Multimedia Interactive Services, International Workshop on
By Werner Bailer, Georg Thallinger
Issue Date:May 2009
pp. 53-56
Besides the reduction of redundancy the selection of representative segments is a core problem when summarizing collections of raw video material. We propose a novel approach for the selection of segments to be included in a video summary based on Hidden M...

Automatic quality control for audiovisual media is an important tool in the media production process. In this paper we present tools for assessing the quality of audiovisual content in order to decide about the reusability of archive content. We first disc...
Learning Multiple Sequence-Based Kernels for Video Concept Detection
Found in: 2012 IEEE International Symposium on Multimedia (ISM)
By Werner Bailer
Issue Date:December 2012
pp. 73-77
Kernel based methods are widely applied to concept and event detection in video. Recently, kernels working on sequences of feature vectors of a video segment have been proposed for this problem, rather than treating feature vectors of individual frames ind...
Real-time Person Tracking in High-resolution Panoramic Video for Automated Broadcast Production
Found in: Visual Media Production, Conference for
By Rene Kaiser,Marcus Thaler,Andreas Kriechbaum,Hannes Fassold,Werner Bailer,Jakub Rosner
Issue Date:November 2011
pp. 21-29
For enabling immersive user experiences for interactive TV services and automating camera view selection and framing, knowledge of the location of persons in a scene is essential. We describe an architecture for detecting and tracking persons in high-resol...
Generic Access to Multimedia Metadata as a Browser Extension
Found in: Multimedia on the Web, Workshop on
By Florian Stegmaier,Werner Bailer,Martin Höffernig,Andreas Eisenkolb,Mario Döller,Tobias Bürger,Harald Kosch
Issue Date:September 2011
pp. 38-39
The variety of multimedia streaming platforms on the Web is ever growing, whereas (metadata) interoperability issues remain unsolved. To address this issue, the World Wide Web Consortium (W3C) launched the Media Annotations Working Group. One output of thi...
Tracking and Clustering Salient Features in Image Sequences
Found in: Visual Media Production, Conference for
By Werner Bailer, Hannes Fassold, Felix Lee, Jakub Rosner
Issue Date:November 2010
pp. 17-24
Many applications in media production need information about moving objects in the scene, e.g. insertion of computer-generated objects, association of sound sources to these objects or visualization of object trajectories in broadcasting. We present a GPU ...
A Comprehensive Infrastructure and Workflow for Acquisition of High-Resolution Multi-view Content
Found in: Visual Media Production, Conference for
By Werner Bailer, Christian Schober, Thomas Brune
Issue Date:November 2010
pp. 25-32
The current success of immersive 3D experiences in feature films and the trend towards 3D TV require advanced tools and workflows for high-quality capture of multi-view live scenes including depth information. These requirements are not fulfilled by today’...
A C++ library for handling MPEG-7 descriptions
Found in: Proceedings of the 19th ACM international conference on Multimedia (MM '11)
By Georg Thallinger, Hermann Furntratt, Peter Schallauer, Werner Bailer, Werner Haas
Issue Date:November 2011
pp. 731-734
We present a C++ library implementing part 2, 3, 4 and 5 of the MPEG 7 multimedia content description standard, including the updated version finalized in 2004. The library supports handling of MPEG-7 descriptions as trees of typed objects, supporting (de)...
Sequence-based kernels for online concept detection in video
Found in: Proceedings of the 2011 ACM international workshop on Automated media analysis and production for novel TV services (AIEMPro '11)
By Werner Bailer
Issue Date:December 2011
pp. 1-6
Kernel methods, e.g. Support Vector Machines, have been successfully applied to classification problems such as concept detection in video. In order to capture concepts and events with longer temporal extent, kernels for sequences of feature vectors have b...
Evaluating detection of near duplicate video segments
Found in: Proceedings of the ACM International Conference on Image and Video Retrieval (CIVR '10)
By Werner Bailer
Issue Date:July 2010
pp. 197-204
The automatic detection of near duplicate video segments, such as multiple takes of a scene or different news video clips showing the same event, has received growing research interest in recent years. However, there is no agreed way of evaluating near dup...
Comparing fact finding tasks and user survey for evaluating a video browsing tool
Found in: Proceedings of the seventeen ACM international conference on Multimedia (MM '09)
By Herwig Rehatschek, Werner Bailer
Issue Date:October 2009
