3D Interactive Free Form Deformations for Facial Expressions
Computer simulation of human facial expressions requires an interactive ability to create arbitrary faces and to provide a controlled simulation of expressions on these faces. The system described in this paper presents the interactive facilities for simulating abstract muscle actions using Free Form Deformations (FFD). The particular muscle action is simulated as the displacement of the contro...
متن کاملA Simple Approach to Interactive Free-Form Shape Deformations
In this paper, we propose a set of free-form shape deformation techniques. The basic approach can be described as follows. Given a surface represented by a mesh and a control point, for every mesh vertex let us consider the difference between the control point and the vertex. The vertex is shifted by a displacement equal to the difference times a scale factor where the scale factor is given by ...
متن کاملModeling Adaptive Deformations during Free-Form Pose Estimation
In this article we discuss the 2D-3D pose estimation problem of deformable 3D free-form contours. In our scenario we observe objects of any 3D shape in an image of a calibrated camera. Pose estimation means to estimate the relative position and orientation of the 3D object to the reference camera system. The object itself is modeled as free-form contour. The fusion of modeling free-form contour...
متن کاملTemporal sparse free-form deformations
FFD represent a widely used model for the non-rigid registration of medical images. The balance between robustness to noise and accuracy in modelling localised motion is typically controlled by the control point grid spacing and the amount of regularisation. More recently, TFFD have been proposed which extend the FFD approach in order to recover smooth motion from temporal image sequences. In t...
متن کاملDynamic Free-Form Deformations for Animation Synthesis
Free-form deformations (FFDs) are a popular tool for modeling and keyframe animation. This paper extends the use of FFDs to a dynamic setting. Our goal is to enable normally inanimate graphics objects, such as teapots and tables, to become animated, and learn to move about in a charming, cartoon-like manner. To achieve this goal, we implement a system that can transform a wide class of objects ...
