compactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولAutomated modelling of real human faces for 3D animation
This paper describes the automated creation of a textured face mask of a natural person suitable for realtime animation. A 3D surface polygon face mask is used. A set of muscles is defined to animate the mask. The mask is adapted to a real person using 3D surface data from a calibrated stereo sensor. Firstly, the facial features of the mask are aligned to the 3D data by scaling the mask. Second...
متن کاملRealistic Speech Animation of Synthetic Faces
In this study, we combined physically-based modeling and parameterization to generate realistic speech animation on synthetic faces. We used physically-based modeling for muscles. Muscles are modeled as forces deforming the mesh of polygons. Parameterization technique is used for generating mouth shapes for speech animation. Each meaningful part of a text,which is a letter in our case,correspon...
متن کاملAnimation of Synthetic Faces in MPEG-4
MPEG-4 is the first international standard that standardizes true multimedia communication including natural and synthetic audio, natural and synthetic video, as well as 30 graphics. Integrated into this standard is the capability to define and animate virtual humans consisting of synthetic heads and bodies. For the head, more than 70 model-independent animation parameters de$ning low-level act...
متن کاملBehavioral Animation of Faces: Parallel, Distributed, and Real-Time
Facial animation has a lengthy history in computer graphics. To date, most efforts have concentrated either on labor-intensive keyframe schemes, on manually animated parameterized methods using FACS-inspired expression control schemes, or on performance-based animation where facial motions are captured from human actors. As an alternative, we propose the fully automated animation of faces using...
