A 3D face model is texture-mapped with a head-on view of the face. Feature points in the face-texture are then selected based on image Hessians. The selected points of the rendered image are tracked in the incoming video using normalized correlation. The result is fed into an extended Kalman filter to recover camera geometry, head pose, and structure from motion. This information is used to rigidly move the face model to render the next image needed for tracking. Every point is tracked from the Kalman filter's estimated position. The variance of each measurement is estimated using a number of factors, including the residual error and the angle between the surface normal and the camera. The estimated head pose can be used to warp the face in the incoming video back to frontal position, and parts of the image can then be subject to eigenspace coding for efficient transmission. The mouth texture is transmitted in this way using 50 bits per frame plus overhead from the person specific eigenspace. The face tracking system runs at 30 Hz, coding the mouth texture slows it down to 12 Hz.","PeriodicalId":237701,"journal":{"name":"Proceedings IEEE International Workshop on Modelling People.

First we make a small set of 3D-virtual faces just using photo data, using a method so called virtual cloning. Then we use very intuitive 3D-morphing system to generate a new population, which is profited from 3D-structure of existing virtual faces. The virtual cloning method uses a set of orthogonal pictures of a person. This efficient method for reconstructing 3D heads suitable for animation starts with the extraction of feature points from the orthogonal picture sets. A previously constructed, animation-ready generic model is transformed to each individualized head based on the features extracted from the orthogonal pictures. Using projections of the 3D head, a 2D texture image is obtained for an individual reconstructed from pictures, which is then fitted to the clone, a fully automated procedure resulting in 360-degree seamless texture mapping. We also introduce an extremely fast dynamic system for 3D morphing with 3D spatial interpolation and powerful 2D texture-image metamorphosis based on triangulation inherited from 3D structure of virtual faces. The interface allows for the real-time inspection and control of the morphing process.","PeriodicalId":237701,"journal":{"name":"Proceedings IEEE International Workshop on Modelling People.
