Generic information

Description

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

Research Areas
• 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 understand-ing
• 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
