A structure-guided conditional sampling model for video resolution enhancement

Abstract: In this paper, a novel approach is introduced to video resolution enhancement based on a structure-guided conditional sampling model. The proposed conditional sampling model is composed of hybrid models to handle strongly structured and weakly structured regions separately. To accomplish this, a binary hidden field indicating image structure is introduced into the conditional reconstruction process for estimating the high resolution video frames from the low resolution video frames. Preliminary results show that the proposed approach has the potential to produce high resolution video frames with improved image quality when compared to existing structure-guided video resolution enhancement approaches.
