학습 기반 내용 적응적 보간법을 이용한 영상의 해상도 향상 기법

In this paper, we propose image up-scaling algorithm using learning-based content adaptive interpolation. At learning stage, various low-resolution and high-resolution image pairs are trained to derive an optimized dictionary of interpolation weights At the inference stage, each pixels block of an input image is synthesized using the trained dictionary. Simulation results prove the superiority of the proposed algorithm.
