Abstract
Luminance changes in a TV image sequence can be interpreted as being due to a scene consisting of 3D-objects moving with 6 degrees of freedom in 3D-space. The 3D-space is illuminated by a light source and is observed by a camera. A parametric model is presented which employs an explicit representation of the illumination source, the camera, and the 3D-objects. A method is suggested, in which an Analysis-by-Synthesis-process automatically extracts the model parameters from an incoming sequence of monocular TV images and thereby allows the modelling of the 3D scene. Since a parametric description of a complex scene resulting in a physically satisfactory modelling cannot be achieved in all generality, we have concentrated on the modelling of quasirigid, natural objects with homogeneous surfaces like the head-shoulder parts of human beings.
