• Abstract: Arbitrary neural style transfer is a vital topic with research value and industrial application prospect, which strives to render the structure of one image using the style of another. Recent researches have devoted great efforts on the task of arbitrary style transfer (AST) for improving the stylization quality. However, there are very few explorations about the quality evaluation of AST images, even it can potentially guide the design of different algorithms. In this paper, we first construct a new AST images quality assessment database (AST-IQAD) that consists 150 content-style image pairs and the corresponding 1200 stylized images produced by eight typical AST algorithms. Then, a subjective study is conducted on our AST-IQAD database, which obtains the subjective rating scores of all stylized images on the three subjective evaluations, i.e., content preservation (CP), style resemblance (SR), and overall visual (OV). To quantitatively measure the quality of AST image, we proposed a new sparse representation-based image quality evaluation metric (SRQE), which computes the quality using the sparse feature similarity. Experimental results on the AST-IQAD have demonstrated the superiority of the proposed method. The dataset and source code will be released at https://github.com/Hangwei-Chen/AST-IQAD-SRQE

  Blind image quality assessment (BIQA) approaches often fall short in real-world scenarios due to their reliance on a generic quality standard applied uniformly across diverse images. This paper introduces PICNIQ, a pairwise comparison framework designed to bypass the limitations of conventional BIQA. By employing psychometric scaling algorithms, PICNIQ transforms pairwise comparisons into just-objectionable-difference (JOD) quality scores, offering a granular and interpretable measure of image quality.

We also propose a method for IQA based on semi-supervised knowledge distillation from full-reference teacher models into blind student models.
