Abstract

For the improvement of joint estimation of 2D motion and 2D object boundaries an optimization procedure based on multigrid and pattern processing is presented. In this procedure an iterative optimization is applied using grids of different resolution, starting with a global estimation of the motion in the coarsest grid. Improvements are achieved by the introduction of boundary patterns, which are obtained from boundary estimates from coarser grids to be used in the finer ones. It is shown that the developed technique compared to a hierarchical blockmatching technique leads to a significant reduction of the mean square error between compensated and original images at object boundaries.
