“…This method creates Van Gogh‐like renderings of images, but generates conflicting strokes orientation that does not take the neighborhood objects into account. Park [PKB*06] and Seo [SPY09] applied the best matching technique based on a photomosaic algorithm to painterly rendering. This method chooses the best matching brush stroke from a database storing a number of brush stroke templates.…”

Previous painterly rendering techniques normally use image gradients for deciding stroke orientations. Image gradients are good for expressing object shapes, but difficult to express the flow or movements of objects. In real painting, the use of brush strokes corresponding to the actual movement of objects allows viewers to recognize objects' motion better and thus to have an impression of the dynamic. In this paper, we propose a novel painterly rendering algorithm to express dynamic objects based on their motion information. We first extract motion information (magnitude, direction, standard deviation) of a scene from a set of consecutive image sequences from the same view. Then the motion directions are used for determining stroke orientations in the regions with significant motions, and image gradients determine stroke orientations where little motion is observed. Our algorithm is useful for realistically and dynamically representing moving objects. We have applied our algorithm for rendering landscapes. We could segment a scene into dynamic and static regions, and express the actual movement of dynamic objects using motion based strokes.

“…Initially, researchers involved in scientific visualization used NPR techniques to express an image in great detail [2]. Since then, there have been researches on creating stylized images with a personal touch, such as cartoons, oil paintings [3], and illustrations [4]. Oil paintings use oils as the medium for producing strokes, whereas illustrations reproduce photographs in the form of hand-sketched images.…”

This paper proposes a wireless LAN-based digital photo frame system that displays photographs with non-photorealistic rendering (NPR) effects. The system accepts a photograph as an input and generates an artistic image using NPR techniques. Then, it displays the final images on a digital photo frame via wireless LAN. By using this system, users can easily view different artistic images by inputting a photograph.
