A Deep Learning Based No-Reference Image Quality Assessment Model for Single-Image Super-Resolution

Abstract

Single-image super-resolution (SISR) is a very important and classic problem of the computer vision community. Although a lot of SISR methods have been proposed, few studies have been conducted to address the quality assessment of SISR methods. In this paper, we proposed a deep learning based no-reference image quality assessment (NR-IQA) model for SISR. We took small patches from images to form our training set and labeled them with different scores. With the aid of well-designed architecture and training strategy, our method achieved a performance leap than state-of-the-art methods. Experimental results proved the generalizability and the effectiveness of the proposed model.
