摘　　要：水彩画的模拟绘制具有一定的难度,为提高水彩画模拟绘制的效果,文中通过分析和研究传统水彩画绘制特征和基本绘制技法,确定水彩画模拟绘制的步骤:边缘提取和暗色化、水彩颜料自由扩散、流动图案产生、纸张纹理融合。提出一种基于Canny边缘检测和八邻域加权平均扩散算法的水彩画模拟绘制方法。利用形态学运算来实现水和色彩相互作用产生的流动图案,最后提出基于像素级的融合算法来实现纸张的纹理效果。从实验效果来看,该方法具有较好的模拟效果和执行效率。The simulation drawing of watercolor paintings has a certain difficulty,and the simulation drawing steps of watercolor paintings such as edge extraction and darkening,free diffusion of watercolor paint,flow pattern generation,and paper texture blending are determined in this paper by analyzing and studying the traditional watercolor painting drawing characteristics and basic drawing techniques,so as to improve the simulation drawing effect of watercolor paintings. A watercolor simulation drawing method based on the Canny edge detection and eight-neighborhood weighted average diffusion algorithm is proposed. The morphological operation is used to realize water and color interaction,so as to generate flow patterns. A fusion algorithm based on the pixel level is put forward in the end to achieve the texture effect of paper. The experimental results show that the method has a good simulation effect and execution efficiency.
