摘　　要：铅笔画是一种发展迅速并受人喜爱的绘图风格,通常由画师手工绘制,但受画手绘画功底限制很大,且用时很长,因此无法满足目前大量平面设计的需求,而利用图像处理技术,可以将自然图像方便、快速地转化为铅笔画。为此,提出一种全自动的铅笔画生成算法,融合自然图像中可变局部边缘模式提取的梯度信息和色调值生成的色调信息,获得包含重要笔画特征的线条画和色度画,并将二者有效融合,生成素描或彩色铅笔画。实验结果显示,该方法不仅能够生成视觉感逼真、信息丰富的铅笔画,同时对噪声、强纹理信息和光照变化不敏感。Pencil drawing is a popular drawing style and develops rapidly,which is usually drawn by the painter.However,it is limited by the painter's painting skills and takes a long time.Therefore,it cannot meet the requirement of a large number of graphic designs.But pencil drawing can be expediently and quickly generated by using image processing technologies.For this reason,a full-automatic pencil drawing generation algorithm is proposed in this paper.Natural image gradient information extracted by varied local edge pattern and tonal information generated from tonal value were fused.The line drawing including important characteristics of stroke and tonal drawing were obtained and effectively combined.The gray or color pencil drawing was generated.The experimental results show that the proposed method not only can generate vivid and informative pencil drawing,but also is insensitive to noise,strong texture information and light variation.
