| Abstract: We propose a super-resolution algorithm based on local adaptation. In the proposed algorithm, the mapping function from the low-resolution images to high-resolution image is estimated by adaptation. Moreover, the property of the high-resolution image is learned and incorporated in a regularization-based restoration. The proposed regularization function is used as a general directional total variation with adaptive weights. The adaptive weights of the directional total variation are estimated based on the property of the partially reconstructed high-resolution image. The regularization function can be thought as a linear combination of smoothness in different directions. The convexity conditions as well as the convergence conditions are studied for the proposed algorithm. | ||
