Abstract

Many Super-Resolution algorithm using DNN have been proposed. They simply expand the image size. On the other hand, bit depth expansion has also been proposed independently. In this paper, we consider the case when the image enlargement process is combined with bit depth expansion by Super-Resolution processing. Experimental results show its validity in both SDR and HDR images.
