【摘要】：铅笔画是一种深受人们喜爱的艺术形式，而彩色铅笔画是铅笔画的一个特殊分支，这一艺术风格正越来越得到人们的欣赏。其粗糙但柔和、略带模糊但轮廓鲜明的质感带给人一种纯朴而又雅致的韵味，其基于线条的风格能够在简约中极具张力地表达所描绘的对象。从自然图片生成各种各样的风格的绘画效果是非真实感绘制（NPR）领域的一个重要研究方向。但至今为止，，已有的方法在模拟真实的彩色铅笔画效果方面都不不太成功。原因在于带有方向信息的纹理不适合表现彩色铅笔画的细腻颗粒效果，而目前也还缺乏对于彩色铅笔画中颜色混合原理的研究与建模。本文研究彩色铅笔画生成中的关键问题，对真实的彩色铅笔以有限的颜色通过视觉上所接受的光学混合来表现出丰富的不同色彩的过程进行仿真。主要包括两部分内容：一是对色彩的量化，对原始图像上连续的色彩，以基本颜色集合进行量化；二是色彩的混合，以光学理论对量化后的色彩进行混合，以表现出变化丰富的色彩纹理。使用这种基于固定数量原色的色彩混合方法，结合不带方向信息的均匀纹理，能够表现出彩色铅笔画的细腻颗粒效果。在此基础上，本文把混合后的色彩与铅笔画纹理相结合进一步生成彩色铅笔画纹理。最后，把此纹理与具有人工绘制特点的线条画进行合成以生成富有表现力的彩色铅笔画效果。
[Abstract]:Pencil painting is a kind of popular art form, and color pencil painting is a special branch of pencil painting, this art style is getting more and more people's appreciation. Its rough but soft, slightly fuzzy but sharp outline gives people a simple and elegant charm, its line-based style can express the objects described in a very tense manner in simplicity. It is an important research direction in the field of non-realistic rendering (NPR) to produce various styles of painting effects from natural images. Up to now, however, the existing methods are not very successful in simulating the real color pencil drawing effect. The reason lies in the fact that the texture with direction information is not suitable to represent the fine particle effect of color pencil painting, and there is still a lack of research and modeling of color mixing principle in color pencil painting at present. In this paper, the key problems in the generation of colored pencils are studied, and the process that real colored pencils show rich and different colors with limited colors through the optically acceptable optical mixture is simulated. It mainly includes two parts: one is to quantify the color, the continuous color on the original image is quantized by the basic color set, the other is to mix the color after quantization with the optical theory. To show a variety of color textures. Using the method of color mixing based on fixed number of primary colors and combining the uniform texture without direction information, the fine particle effect of color pencil drawing can be shown. On this basis, this paper combines the mixed color with the pencil-drawing texture to generate the color pencil-drawing texture. Finally, the texture is combined with the line drawing with manual drawing to produce the expressive color pencil drawing effect.
