Special projects include the analysis of view-dependent particle distributions for placing stipples on the surface of polygonal meshes as well as real-time visibility preprocessing to improve interaction with large models. Computer games: As application of real-time NPR techniques, current research focuses on the integration of various different rendering styles in a game engine, evolving game engines into a versatile tool for real-time visualization. Techniques for action summaries, the automatic generation of summaries of interactive scenes are developed. For that, characteristics of players and exciting events that occur are detected so

Alzheimer's Disease Overview Alzheimer's disease (AD), is one form of dementia that gradually gets worse over time. It affects memory, thinking, and behavior. Memory impairment, as well as problems with language, decision-making ability, judgment, and personality, are necessary features for the diagnosis. Reference from A.D.A.M.
