Automatic generation of personalized human avatars from multi-view video

In multi-user virtual environments real-world people interact via digital avatars. In order to make the step from the real world onto the virtual stage convincing the digital equivalent of the user has to be personalized. It should reflect the shape and proportions, the kinematic properties, as well as the textural appearance of its real-world equivalent. In this paper, we present a novel spatio-temporal approach to create a personalized avatar from multi-view video data of a moving person. The avatar’s geometry is generated by shapeadapting a template human body model. Its surface texture is assembled from multi-view video frames showing arbitrary different body poses.
