A new approach for lighting effect rendering

Abstract

We propose a new approach to render different lighting effects on an image. Artists often use different stylizations for different lighting effects in the same image. However, existing work just try to extract shadows without distinction of their type. We introduce a lighting map to describe the different lighting effects and propose six non-photorealistic rendering based on artistic styles ranging from Chiaroscuro to comics. Giving an input image, we are able to automatically generate a lighting map which may be modified by the user to specify the types of shadow or light effects. Our model is flexible and specifically designed to help users and even amateur users, to semi-automatically stylize the different kinds of light effects in an image. It is designed to be integrated into an image editing tool. © 2010 Springer-Verlag.
