Abstract:
In multimedia environments, digital artwork is usually exhibited on many types of media with different sizes and resolutions. For this reason, it is desirable that artists create works of art in a resolution independent way. We present an algorithm for resolution independent unrealistic imaging. To realize resolution independent imaging, characteristics of all brush strokes are coded and saved in a characteristic table. From the characteristic table, images of any size and resolution can be created. This characteristic table gives our algorithm the ability to create many types of artistic expression. Three different expressions are exhibited. In particular the expression in which contours are drawn by pen and ink then colored by brush is, we believe, a new type of expression in computer artwork. Another feature of our algorithm is that the shape of a brush stroke is not set, but is adaptively changed: a less mechanical pattern which seems more natural to humans. As for aesthetic evaluation, we do not have a proper evaluation method, but if an image created using this algorithm won an award for digital creation, that would be an indication of the algorithm's success.
