Background and purpose: Dental caries are highly prevalent and their exact detection at initial stages is necessary. The laser-based DIAGNOdent device is used to detect these caries. The aim of this study was to assess the level of agreement between visual observation, bitewing radiographs, and DIAGNOdent system in detection of proximal caries in clinical applications. Materials and methods: I...

Meaningful objects in a scene move with purpose. The ability to induce visual expectations from such purpose is important in visual observation. By regarding the spatio-temporal regularities in the moving patterns of an object in the scene as a network of temporally dependent belief hypothesis, visual expectations can be represented by the most likely combinations of the hypotheses based on upd...
