An effective method of image registration for super-resolution

In Super-Resolution, the combination technique of frequency domain and the improved keren's method has been applied in the sub-pixel image registration. The method proved to be accurate in movement estimation within given precision, but the registration accuracy was affected by the relative parameters. Based on the traditional method, an effective method of image registration for Super-Resolution in the paper was proposed in the paper. The proposed registration method has good performance by introducing the registration evaluation parameter. The experimental results demonstrate that the proposed method is effective for different test images, which takes into account the precision of estimation results and the computation efficiency as well.
