The visual system precisely represents complex scene ensembles

Video Scene Segmentation System Using Audio-visual Features

This work demonstrates a new approach to video temporal segmentation into scenes. The utilized technique is based on an audio-visual extension of the well-known method of the Scene Transition Graph (STG). This multi-modal extension exploits both lowand high-level audio-visual descriptors to construct distinct STGs. These STGs are employed into a probabilistic framework that is used for estimati...

Visual Scene Perception

A visual scene is commonly defined as a view of an environment comprised of objects and surfaces organized in a meaningful way, like a kitchen, a street or a forest path. More broadly, the domain of scene perception encompasses any visual stimulus that contains multiple elements arranged in a spatial layout, for example a shelf of books, an office desk, or leaves on the ground. As a rough disti...

Active visual scene exploration

This thesis addresses information theoretic methods for control of one or several active cameras in the context of visual surveillance. This approach has two advantages. Firstly, any system dealing with real inputs must take into account noise in the measurements and the underlying system model. Secondly, the control of cameras in surveillance often has different, potentially conflicting object...

Learning Visual Scene Attributes

Take a look around you. How would you describe your surroundings to best give an idea of what everything looks like to someone not there? Maybe you will give a category to the scene, say, ‘bedroom’. You might try to list some of the objects around you, like ‘bed’, ‘lamp’, and ‘desk’. Or perhaps you’ll describe it with adjectives like ‘indoors’, ‘cozy’, and ‘cluttered’. In computer vision, (or m...
