  Background
Abstract A real-time non-photorealistic rendering technique that generates a sketch from a real photograph is presented in this paper. In accordance with the features of sketch and human vision, the authors draw the contours according to the conceptual color difference, and generate the shadow with the importance map which is produced from the intensity of light, and combine them to create the final desired sketch. Compared with current methods, the framework design doesn¡¯t demand human-computer interaction, and can get better visual effects as well as allow real-time implementation.
