摘　　要：该文提出了一种改进的铅笔画生成方法。该文改进了用于提取轮廓的霓虹算法,改进方法能够在保证效果的前提下,降低算法的复杂度,提高了图像处理的效率。提出了一种新的纹理产生方法,根据亮度将图像分层,然后对每一层添加噪声并进行适当的USM锐化,最后应用运动模糊对每一层图像生成不同方向的纹理。实验结果表明,该方法相比传统的铅笔画生成方法能够更快速的将输入图像转换为铅笔画,并能取得令人满意的效果。This paper proposes an improved method for generating pencil drawing .We improve the neon algorithm applied to contour extraction. In this way, good image processing results can be obtained with low algorithm complexity and high image processing efficiency.We propose a new method of texture generation.We divide a source image into layers of successive intensity ranges,add noise and use usm sharpening to each layer .At last apply the motion blur for all layers,generate stroke images with dif- ferent texture directions.The experiment shows that this method can turn the input image into pencil drawing with a higher speed,and the processing result is also satisfying.
