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 jlow-oriented morphing(More)
Until now there are many models for rendering water and other #uids, especially to generate the curved surfaces of #exible objects such as liquids, gases and snow. Metaball formulation is widely used because of its simplicity and #exibility. This paper proposes a new method for generating water droplets, which allows for general deformation in a(More)
Interactive and realistic rendering of various effects which are appeared in the real world paintings can be used for several applications such as animation or education. For Western paintings, watercolor or oil paintings have been main subjects for representation and model-based approaches have been researched. In case of Oriental paintings, numerous(More)
Automatic character recognition and image understanding of a given paper document are the main objectives of the computer vision field. For these problems, a basic step is to isolate characters and group words from these isolated characters. In this paper, we propose a new method for extracting characters from a mixed text/graphic machine-printed document(More)
Ink-and-wash landscape painting in oriental has distinctive features to depict landscape comparing to the western painting. The pine tree is a main theme in oriental painting and its oriental style rendering remains unsolved problem to simplify the complex structure of its leaf based on image. In this paper, we propose a novel rendering method for(More)
Realistic representation of various effects which are appeared in the real world paintings can be used for several applications like as animation or education. To generate Oriental paintings, numerous studies have focused on model-based approaches. In this paper, a new modelbased approach for Oriental paintings is described. To represent the diffusion(More)
