基于图像的铅笔画绘制技术的研究现状与展望

非真实感绘制(Non-Photorcalistic Rendcring,NPR)是计算机图形学领域的一个分支，旨在使用计算机来生成具有某种艺术效果的作品。目前，非真实感绘制技术已经能够成功地模拟油画、水彩画、卡通画、铅笔画等艺术风格，在许多领域得到很广泛的应用。铅笔素描是艺术造型的基础。作为一种最简单的艺术表现形式，铅笔画凭借其简洁流畅的特点深受广大艺术爱好者的喜爱。如今，基于图像的铅笔画绘制技术已经是NPR领域的一个重要组成部分，受到诸多研究人员的关注，但该技术仍处于成长阶段，算法的通用性还无法满足现实应用的需求。

Survey of Image-based Pencil Rendering Technique

Non-photorcalistic rendering is a branch of computer graphics,which is committed to generate some art style works. Currently,non-photorealistic rendering technology (NPR) has been able to successfully simulate the oil paintings, watercolors, cartoons, pencil and some other styles, and has been widely used in many areas. Pencil sketch is the basis of art modeling. Since usually simple and smooth, pencil works arc deeply loved by people. However, it is not easy for every person to master the skills of pencil drawing. Imag}based pencil rendering technique is an important part of NPR, and is more and more concerned by researchers. 13ut related technologies arc still immature, and can' t meet the needs of practical applications.
