Abstract
Some algorithms for motion estimation of two frame consecutive images applied to super⁃resolution image recon⁃struction are described in this paper,in which the block matching algorithm(BMA)and phase correlation algorithm are studied. The three⁃step search strategy and fast search strategy of BMA are researched mainly. The experiment results show the change of image grey is continuously stable when BMA translation amount is in a certain range,but it is easy to fall into local minimum in the compression processing of image sequences. The phase correlation algorithm is to estimate the relative movement of two images by Fourier frequency domain method. The experiment results indicate that the phase correlation method not only can be used in translational movement,but also can be used for motion estimation of rotational movement by coordinate transformation.关键词
