摘要
提出了一种对彩色相片进行渲染的方法，使得其输出效果接近艺术家徒手做图效果．在笔画生成算法中，通过分析彩色图像象索邻域在CIE-Lu^·V^·。颜色空间的色差图的0～2阶矩，得出表达源图像的彩色笔画的分布及笔厕参数．然后用α混合按先绘制粗笔画，后绘制细笔画得出渲染图。
A color photograph rendering method is proposed in this paper, which method produces artistic hand drawing effects. Instead of image intensity gradients, local color difference in CIE-Lu ^·V^·color space and 0-2 order image moments are use.d for the calculation of stroke distribution and stroke parameters. Strokes are painted via a blending, in which finer stokes are painted after larger ones. This rendering method can be applied to computer art design and computer aiding fine arts education.
