Description

The goal of the DEVA group is the interpretation and organization of information coming from distributed multimodal sensors. Sensors can be dynamic or static imaging devices or other multimedia sources. By spatio-temporal analysis of information we recognize and classify events. These events are e.g. unusual motion patterns, behavior change in time series, voice patterns. We place special emphasis on machine learning, data mining, human perception, geometrical optics, mutimodal sensor fusion, optimization methods and variational analysis in areas such as image and video processing, biometrical identification, connections with sensor networks and computer graphics.

Main Research Areas

• Pattern and event recognition,
• 3D scene analysis and LIDAR measurement technology,
• Ontology based classification and indexing of multimedia events,
• Recognition and tracking of biometric features,
• Energy based image and video segmentation,
• Stochastic models and learning methods for event analysis,
• Automatic camera registration, event matching of multiple views, optics-oriented image understanding,
• Self organizing distributed sensor-networks and related calculations, operation optimization,
• Cognitive vision problems in visibility, compression, recognition, visualization of artistic effects,
• Detection and removal of artifacts from still images: shadow regions, reflections, undesired objects,
• Surveillance related modelling and recognition.

Major results

New probabilistic methods have been proposed for the interpretation and analysis of 2D and 3D visual information obtained from real-world scenes
- Separating moving objects from the background and shadow detection in 2D and 3D
- Shape and texture separation with adaptive filtering techniques
- Obtaining range information by fusing various sensors and modalities
- Change detection and built in area analysis in aerial and satellite images
- Motion and gesture based biometrical identification

Products/services

Consulting and development in teh following areas:
* 3D/4D reconstruction - i4D dynamic 3D city models, which can be observed from arbitrary viewpoints, modified by user interaction, and they can visualize events observed from the real-world (4D animations)
* security surveillance program packages
* algorithm library for the analysis of customer behaviour and for event detection for indoor environment
