Description

An arbitrary direction face image reconstruction method using real images is proposed as a basic technology for virtual space teleconferencing systems. This method combines the conventional model-based and image-based approaches to enable the process with high speed and high precision. The input human face position and direction is measured using image processing techniques, and re ected upon a three-dimensional face model. By mapping the texture of the camera input image directly onto the model, realistic human face images could be reconstructed. Also, by mapping the input images consecutively in sequence, changes in facial expression could be approximated. A fundamental experiment using a home-use video camera and a relatively low-speed workstation showed the efficiency of the proposed method.
