Abstract
In this paper, a fast global motion estimation method is proposed for panoramic video coding. This method accelerates the procedure of global motion estimation (GME) during inter-frame prediction by using two techniques: 1) a compact motion model, which uses only three motion parameters to represent accurately the global motion among the successive panoramic frames. 2) A GME filter, which filters the blocks unreliable and contributing less to the GME, based on a threshold method. The experimental results show the proposed fast global motion estimation method manages to speed up the processing of estimating the motion vector field while maintaining the coding performance.
