While high resolution images are required for various applications, aliased low-resolution images are only available due to the finite sensor pixels. In this paper a new approach is proposed to obtain superresolution using regularization. With the proposed approach based on the discrete cosine transform, high-resolution images can be efficiently reconstructed both in the underdetermined case and in the case with inaccurate motion estimates
