Xialei Liu, Joost van de Weijer, Andrew D. Bagdanov
2017 arXiv   pre-print
We propose a no-reference image quality assessment (NR-IQA) approach that learns from rankings (RankIQA).  ...  To address the problem of limited IQA dataset size, we train a Siamese Network to rank images in terms of image quality by using synthetically generated distortions for which relative image quality is  ...  We call this learning from rankings approach RankIQA, and with it we learn to rank image in terms of quality using Siamese Networks, and then we transfer knowledge learned from ranked images to a traditional  ...
