Along with the fast development of image style transfer, large amounts of style transfer algorithms were proposed. However, not enough attention has been paid to assess the quality of stylized images, which is of great value in allowing users to efficiently search for high quality images as well as guiding the designing of style transfer algorithms. In this paper, we focus on artistic text stylization and build a novel deep neural network equipped with multitask learning and attention mechanism for text effects quality assessment. We first select stylized images from TE141K dataset and then collect the corresponding visual scores from users. Then through multitask learning, the network learns to extract features related to both style and content information. Furthermore, we employ an attention module to simulate the process of human high-level visual judgement. Experimental results demonstrate the superiority of our network in achieving a high judgement accuracy over the state-of-the-art methods.
Overview of our proposed quality assessment pipeline. The content and style encoders are first obtained by multitask pretraining, and then used for attention quality assessment.
