Abstract
As mobile devices have been rapidly spread up throughout the world, various services have been provided through mobile devices recently. Many services of them have been developed by using built-in sensors mounted on the mobile devices. Non-photorealistic rendering techniques have been also applied to mobile devices for the purpose of user friendliness or attractions. This paper proposes non-photorealistic rendering method using built-in orientation sensor of mobile devices. The method makes changes of non-photorealistic rendering effects in real time by adjustment of vector fields according as coordinate values from orientation sensor get changed on a mobile device. The proposed method renders pen sketch for a given photo image with direction and strength of line strokes which are applied by vector fields. The method executes rendering based on enhanced LIC filter to make pen sketch on a mobile device. Finally, this paper proves efficiency through the experimental results and shows usefulness of the proposed method.
