中文摘要：

改进了非真实感铅笔画艺术效果的绘制算法,利用图像分割、线积分卷积技术确定线条纹理的方向,模拟得到局部区域铅笔画的笔划纹理。采用轮廓线增强、灰度色调控制最终铅笔画艺术效果的边缘信息和灰度色调。通过色彩传输技术得到具有彩色铅笔画的艺术效果。

英文摘要：

The paper gives an overview of the research on NPR methods for computer-generated automatically pencil drawing from 2D images.The approach to simulate pencil drawing is inspired by the similarity between the stroke textures of pencil drawing and the pencil textures generated with line integral convolution.Experimental results show that the proposed method can be used efficiently to create both of the traditional or multicolored pencil drawing.
