| 摘 要: 针对传统生成方法导致准规则斑图不具有美感的问题，从图形结构及色彩层面提出一种提升准规则斑图美感的方法。首先，为减少“窄色带”分布，以等高线分割区间内像素数的方差最小化为目标，优化出一种合理的等高线分割方式。其次，通过映射函数将等高线分割区间的色彩定义在色彩谐和模板的扇区范围内，最终生成富有美感的准规则斑图。实验结果表明，该方法能够生成结构协调的图形，且在用户研究中的指标评分也比传统方法提高了近1 倍，使准规则斑图能够更好地应用于花型设计。 |

| Abstract: Aiming at the problem that the quasi-regular pattern is not aesthetically pleasing due to the traditional generation method, this paper proposes a method to improve the aesthetics of the quasi-regular pattern from the aspect of graphic structure and color. First, in order to reduce the "narrow color band" distribution, a reasonable contour segmentation method is optimized with the goal of minimizing the variance of the pixel number in the contour segment interval. Secondly, the color of the contour segmented interval is defined within the sector range of the color harmony template through the mapping function, and finally an aesthetic quasi-regular pattern is generated. Experimental results show that the proposed method can generate well-structured graphics, and the index score in user research is nearly doubled compared with the traditional method, which makes the quasi-regular pattern better applied to flower pattern design. |
