High Frequency Component Compensation based Super-Resolution Algorithm for Face Video Enhancement
This paper proposes a video-based super-resolution algorithm by high-frequency component compensation. Normalized logarithm distance (NLD) minimization on local shape feature is proposed for image registration. Lost high-frequency information are estimated using the registered frames. By compensating the high-frequency component, the high-resolution images are recovered. The algorithm has lower computational cost than the alternatives. Experimental evaluation verified the usefulness of the algorithm.
