Non photorealistic rendering produces more attractive images, often mimicking artistic work. For artistic effect these aim to extract salient features and structures (e.g. regions, lines) and enhance/re-render them in various ways, whilst suppressing other less salient detail. The results can be used not only for personalising consumer photographs, but also for scientific illustration. The aim of the project is to develop non photorealistic rendering algorithms on mobile devices (phones and tablets) by taking into account different user interface and optimisation for mobile devices.
