应用运动模糊方法仿真铅笔画纹理

通过分析真实铅笔纹理的特点,提出了一种基于运动滤波器的仿真铅笔纹理的新方法.首先对用户输入的图像进行边缘检测,提取轮廓信息,然后对传统白噪声生成法进行改进,将参考图像由RGB色彩空间转换到HSV色彩空间,通过亮度值控制噪声点的产生几率,最后应用运动模糊方法代替传统的线积分卷积(LIC)方法模拟铅笔纹理,得到具有素描风格的结果图像.实验结果表明,该方法生成效果接近于手绘风格,且无需用户交互,适合于动画制作等很多领域的应用.

Method for simulation of pencil drawing based on motion blur

A pencil texture generation method based on motion filter is presented through analyzing the character of the real pencil texture.First, we need to extract the contour lines. Second, to convert RGB values to HSV color space then use the luminance values to guide the distribution of the white noise. Finally, the motion blur algorithm is applied to get effects of pencil drawing. The results show that our method can generate effects closer to real pencil drawing which is suitable for personalized photo.
