For painters, beauty is embodied in realism and abstraction of reality. For AI, beauty is the inheritance and reconstruction of pixels and elements, which is a form of digital artistic expression. We mainly use style transfer technology. Style transfer needs to learn or separate "style" from artistic painting images, and combine this style with the content of target photography pictures, the real image taken by the camera can be converted into a landscape painting style picture, and the left picture is the picture we converted with this technology. As long as there are enough data sets for AI to learn and continuously extract the beautiful elements in paintings, it can be like a human brain, creating according to the photos taken by a given camera to form art works with corresponding styles. With the combination of science and technology and artificial intelligence, we take China's famous natural landscape as a collection of works, and use style transfer to convert the real images taken by the camera into landscape painting style pictures. There is no heavy ink and color, and there are no various complicated painting methods. Simple colors outline a landscape painting. Compared with ordinary photos, landscape painting gives people a more antique charm, so that simple photos can also become a work.
