Learning-based image interpolation via robust k-NN searching for coherent AR parameters estimation ?
Learning-based image interpolation using precise and robust k-NN searching for an accurate AR modeling. Robustness to insufficient k-NN matches and adaptation to relevant k-NN matches during online searching. Online coherent soft-decision estimation of both local AR parameters and high-resolution pixels. Highly competitive performance compared with the state-of-the-art approaches in terms of PSNR and SSIM.
