Modeling of elastic articulated objects and its parameters determination from image contours

Abstract

This paper presents a new method of elastic articulated objects (human bodies) modeling based on a new conic curve. The model includes 3D object deformable curves which can represent the deformation of human occluding contours. The deformation of human occluding contour can be represented by adjusting only four deformation parameters for each limb. Then, the 3D deformation parameters are determined by corresponding 2D contours from a sequences of stereo images. The algorithm presented in this paper includes deformable conic curve parameters determination and the plane, 3D conic curve lying on, parameter determination. © Springer-Verlag Berlin Heidelberg 2005.
