For global motion estimation process is often accompanied by the influence of local campaign,this paper puts forward a global motion estimation algorithm based on LMedSLS.It gets the corresponding characteristics of the coordinates of the piece from two adjacent frames,uses it in affine transformation model,estimates the global motion parameters,and completes image registration through the bilinear interpolation according to the motion parameters.Experiments show that compared with LMedS algorithm,it is improved in both the accuracy and effectiveness.
