| 摘 要： | 流线形风格化图像是印象派风格的典型代表,其艺术特点是通过流线条表现狂野与活泼的流动感,又通过色彩的层叠感表现时空的凝滞性.提出一种流线形风格化图像绘制算法,通过提取目标图像的结构矢量场,利用欧拉弹性模型进行光顺化得到流线场;通过结合凹凸映射的多源光照渲染和色彩扰动得到色彩层叠感强的纹理图;然后利用线积分卷积方法对流线场和纹理图进行合成,并利用样本梵高图像进行颜色传输得到最终的绘制结果.实验结果表明该算法自动化程度高,绘制结果具有较好的流线流动感和色彩层叠感.

| Abstract: | Streamline style oil paintings are the representative oil painting with impressionist effect.Their artistic expression can often convey by the feeling of wide and vivid streamline structure and space-time stagnate through color wash layering.A new automatic algorithm for rendering streamline style paintings is proposed in the paper.In this algorithm,the structure vector field is firstly extracted and then smoothed with the Euler's elastic model to obtain the streamline field,and the texture map with hierarc... |
