Zusammenfassung der Projektergebnisse

This project presents an image-based talking head which provides a higher level of realism when compared to 3D model-based talking head. We first improve the image-based reference talking head system. Based on the optimized system, the image-based talking head system is extended with facial expression synthesis and head motion synthesis, so that the talking head is even more realistic and lifelike. In this DFG project, we have improved the basic facial animation system. Furthermore, the facial animation system is extended with realistic facial expression and added with flexible head motion. Combined with a dialog system, the developed expressive talking head, integrated with eye animation, will open a wide space for many applications, such as web-based customer service, E-education, and E-care. The expressive talking head is able to give a very personalized and believable interface for human-machine communication. These intuitive and efficient interfaces will be extensively used in the near future. The sources of the expressive database and all animations in the project are listed as follows. The animations and recorded videos can be found on our web server. • Basic animations: http://www.tnt.uni-hannover.de/project/facialanimation/demo/mouth • Facial expression synthesis: http://www.tnt.uni-hannover.de/project/facialanimation/demo/emotion • Head motion synthesis: http://www.tnt.uni-hannover.de/project/facialanimation/demo/headmotion • The expressive database is made available to the facial animation community for scientific purposes.
