This paper proposes a new, efficient and a practical way to extract lens zoom camera pan and camera tilt information using modified motion analysis. The proposed method is called the Video Tomography Method(VTM), in which tomography techniques are introduced into a motion estimation algorithm. With the VTM, one is able to visualize motion as a spatiotemporal flow for motion analysis. The VTM is an extremely robust [resistant to noise] method for estimating camera operation due to its tomographic nature. Other possible applications that use extracted motion data for handling video are discussed. This method is targeted towards video handling applications that attribute extracted motion data into a video index. Scene reconstruction techniques can be extended to apply to the problem of resolution enhancement.
