The automatic segmentation and structuring of videos present technical challenges due to the large variation of content, spatial layout, and possible lack of storyline. In this paper, we propose a spectral method to group video shots into scenes based on t ...
Explains methods to provide autonomous virtual humans with the skills necessary to perform stand-alone roles in films, games and interactive television. We present current research developments in the virtual life of autonomous synthetic actors. After a br ...
One of the fundamental and puzzling questions in vision research is how objects are segmented from their backgrounds and how object formation evolves in time. The recently discovered shine-through effect allows one to study object segmentation and object f ...
The human visual system computes features of moving objects with high precision despite the fact that these features can change or blend into each other in the retinotopic image. Very little is known about how the human brain accomplishes this complex feat ...
Accessing and organizing home videos present technical challenges due to their unrestricted content and lack of storyline. In this paper, we propose a spectral method to group video shots into scenes based on their visual similarity and temporal relations. ...
In crowding, neighbouring elements impair the perception of a target. Crowding is often considered a consequence of spatial pooling of visual information. We investigated the role of configural effects in crowding by manipulating the global stimulus config ...
We present current research developments in the Virtual Life of autonomous synthetic actors. After a brief description of the perception action principles with a few simple examples, we emphasize the concept of virtual sensors for virtual humans. In partic ...
We show that the flash-induced fading effect can be influenced by grouping based on colour and shape similarity. In flash-induced fading, peripherally presented elements perceptually disappear after a flash has been presented around or next to the element( ...
In this paper, we present current research developments in the area of autonomous virtual actors. We first define formal requirements for true virtual humans. After a brief description of the perception action principles with a few simple examples, we emph ...
