Oil painting rendering changeable by light effect

Abstract

Traditional oil painting works enable the spectators to feel the various impressions because it can be shown differently by the changes of light effect. The reason of oil painting's distinguishing feature is that it contains the texture and volume of color expressed by thickness of used pigments and brushing. In this paper, we present a novel method that reproduces oil painting-like image from a source picture based on a virtual light and nonphotorealistic rendering technique. To generate the oil paintinglike image as an output, the system first performs stroke distribution, which is to determine where a brush is located for stroking, using edge detection and image segmentation on an input picture. And the intermediate image is constructed with the suitable color, orientation and size of brush at each stroke point. At last, the system applies light effect to the intermediate image and generates the oil painting-like image.
