Paper Abstract

In this paper we describe an algorithm for image interpolation that takes into account the global motion of the camera. A description of the motion field in terms of pan and zoom parameters (global motion) and displacement of independent moving objects (local motion) is carried out. First the estimated global parameters are employed to compensate the images of the camera motion. Then the missing images are interpolated using the local motion information. As a last step the images are reconstructed in their correct dimension considering the global motion information. The performances of the proposed algorithm has been tested within a multilayer video coding scheme. The simulation results show the effectiveness of the proposed motion compensating interpolation algorithm that uses global-local description of the motion field.
