Paper Abstract

Global motion estimation (GME) has attracted great attentions because of its broad applications in video coding, image stabilization, object segmentation and detection. In this paper, Fourier transform formula of the image after global motion with a 6-parameter affine model is deduced, and its special cases for the 4-parameter and 5-parameter affine model are discussed. A method for the global motion estimation using the 5-parameter affine model is proposed based on the Fourier transform properties of the tow images before and after global motion. Simulation results show that the 5 affine parameters can be satisfactorily estimated.
