Abstract

This paper describes a procedure for model-based coding of all channels of a multiview image sequence. The 3D model is initialized by accurate adaption of a 2D wireframe model to the foreground object of one of the views. The rigid 3D motion is estimated for each triangle, and spatial homogeneity neighborhood constraints are used to improve the reliability of the estimation efficiency and to smooth the motion field produced. A novel technique is used to estimate flexible motion of the nodes of the wireframe from the rigid 3D motion of each triangle and flexible deformation of each node of the wireframe. The performance of the resulting 3D flexible motion estimation method is evaluated experimentally.
