Our objective is to create an artificial artwork from photographs, for example by transferring the appearance of famous paintings such as Van Kof’s paintings to user-supplied photographs. This type of application is called style transfer. However, famous style-transfer algorithms need lots of time to produce one image, it maybe takes 30 minutes running on a normal PC. So my project focus on reproducing the image in seconds.").launch()
