“…The pioneering work of Gatys et al [2016] first demonstrated the strength of Deep Convolutional Neural Networks (DC-NNs) in artistic style transfer, where the content and style can be expressed as multi-level feature statistics extracted from the pre-trained DCNNs. Since then, extensive works have been proposed to improve the performance of artistic style transfer in several aspects, such as efficiency [Johnson et al, 2016;Ulyanov et al, 2016], quality [Li and Wand, 2016a;Ulyanov et al, 2017;Zhang et al, 2019;Chen et al, 2021b;Chen et al, 2021a], generalization [Chen and Schmidt, 2016;Li et al, 2017b;Sheng et al, 2018;, diversity [Li et al, 2017a;Ulyanov et al, 2017;Chen et al, 2021c], and controllability [Babaeizadeh and Ghiasi, 2018;Yao et al, 2019].…”
