| 摘 要： | INTRODUCTION Non-photorealistic rendering (NPR) is a domain of computer graphics that has received more and more attention in the past decade. Different from realistic rendering, NPR concentrates on communicating the main context of an image and explores the rendering effect of the scene with the artistic styles, rather than seeking subtle geometry details and naturally physical attribute. Many research efforts were dedicated to simu- lating the traditional media (Hertzmann et al., 2001…

| Abstract: | We present an approach for generating paintings on photographic images with the style encoded by the example paintings and adopt representative brushes extracted from the example paintings as the painting primitives. Our system first divides the given photographic image into several regions on which we synthesize a grounding layer with texture patches extracted from the example paintings. Then, we paint those regions using brushes stochastically chosen from the brush library, with further brush color and shape perturbations. The brush direction is determined by a direction field either constructed by a convenient user interactive manner or synthesized from the examples. Our approach offers flexible and intuitive user control over the painting process and style. |
