Summary:
We present a compressed-domain global motion estimation (GME) algorithm that uses a robust estimator. Conventional GME algorithms based on the M-estimator are accurate and powerful, but are slow because they use an iterative process. To speed up the GME, we propose a non-iterative algorithm that exploits an outlier rejection mask and histogram. In simulations the proposed algorithm was about five times faster than the conventional algorithm and had slightly higher estimation accuracy.
