A novel method for turning an image into simple line drawings is presented. Our technique consists of three parts: line extraction, line rendering and style translation. First it proposes a novel line extraction method based on mathematical morphology thinning and assembles the discrete pixels into stroke paths. Then it considers the feature scale with which the level-of-detail of lines is controlled in the rendering. Finally it gives out a method to generate exaggerated-style line drawings. Experimental results show that our technique can generates vivid line drawings from images.
