Registration methods for harmonious integration of real worlds and computer generated objects

Abstract

This page is an extension of our paper entitled "Registration methods for harmonious integration of real and computer generated objects". We focus in this paper on the problem of adding computer-generated objects in video sequences. We propose a robust method for viewpoint computation which utilizes 3D knowledge on the scene as well as 2D/2D correspondences of key-points. Next, we extend this method to the case of unknown focal length varying from image to image. Finally, we describe how to solve possible occlusions between the computer generated objects and the real scene. Many videos illustrating these different points are presented here.
