Creating pen-and-ink illustration using stroke morphing method

Most illustration systems need a lot of user strokes to generate natural-looking pen-and-ink illustrations. In order to reduce the number of user strokes necessary, we propose a new method for pen-and-ink illustrations using a stroke morphing concept. For this, we introduce a general stroke morphing procedure, which consists of both flow-oriented morphing and shape-oriented morphing. Using this morphing technique, we can make more natural-looking pen-and-ink illustration with fewer user strokes. This work can be applied to generate simplified pictures for dictionary typesetting. The main purpose of this paper is to describe this method, which requires fewer user strokes than other previous methods. Experimental results are given in the final section.
