Abstract
This paper describes an improved method for combined motion and disparity estimation applied to 3DTV signal processing in order to compute temporally and perspectively intermediate pictures. Motion and disparity estimation is based on a modified block matching algorithm taking into account the inherent coherence relation between disparity and motion. Appearing and disappearing areas caused by motion and disparity are detected as well. This information is used to switch between different interpolation and extrapolation modes for computing intermediate pictures. A set of stereo-sequences has been processed by computer simulation. Using the proposed concept with only two cameras a continuous motion parallax can be obtained by signal processing.
