“…Recently, convolutional neural network (CNN) [13] based style transfer methods have shown successful applications in transferring the style of a certain type of artistic painting, e.g, Vincent van Gogh's "The Starry Night", to a real world photograph, e.g., an image taken by iPhone. Since the seminal work of Gatys et al [7], it has attracted a lot of attentions from both academia [10,15,23,24,8,28,31,6,5,4] and industry [26,1,11,3]. Although the work of neural style transfer has shown promising progress on transferring artistic images with rich textures and colors, e.g., the oil paintings, we observe that it is less effective in transferring Chinese traditional painting.…”
