| 摘 要： | 提出了一种新的基于线性卷积积分(Line Integral Convolution)自动铅笔画生成方法。提出的方法改进了已有的铅笔画生成方法,首先利用基于图的图像分割方法实现快速有效的区域分割,其次提出一种新的基于区域的白噪声和纹理方向生成方法。实验表明提出的方法更接近于真实的铅笔画效果。

| Abstract: | This paper proposes an extension to the existing automatic pencil drawing generation technique based on Line Integral Convolution(LIC).We propose in this paper to improve the existed LIC-based method. First, a more accurate and rapid graph-based image segmentation method is introduced to divide the image into different regions.Second,we present a new region-based way to produce white noises and texture directions.We also demonstrate the enhanced LIC pencil drawing is closer to the real artistic style. |

| Keywords: | pencil drawing line integral convolution image segmentation Non-Photo-Realistic rendering(NPR) |
