基于目标轮廓分割的图像卡通风格渲染仿真分析

Research on Image Rendering with Cartoon Style Based on Target Contour Segmentation

针对传统的电视图像卡通风格渲染制作受场所、设备的限制以及依赖人工绘制的周期长、效率低的不足,提出了一种基于目标轮廓特征的图像卡通风格渲染算法。根据卡通图像的特点,在进行卡通风格图像渲染时重点考虑图像中目标的轮廓和区域颜色均一的特点。提取图像中的区域轮廓,完成轮廓的闭合处理,进而实现区域分割,再对局部区域进行颜色均一化处理,并将颜色填充图与轮廓图融合,最终实现图像卡通风格渲染。仿真实验结果表明,与前人提出的基于扫描线的卡通渲染算法相比,方法由于采用了轮廓闭合处理,能克服扫描出现的颜色突兀跳变与虚假条纹,整体卡通风格更均衡,有一定的实际应用价值。

The traditional TV cartoon style image rendering productions are limited by place and equipment. A new image rendering algorithm with cartoon style was proposed based on target contour features. According to the characteristics of the cartoon image, the contour of the target image and the characteristic of uniform region color were considered particularly. The region contour of image was extracted, and the closed contours processing was accom- plished. The regional segmentation was realized. The color homogenization processing was taken in the local region, the color blank maps and contour maps were fused. Compared with the traditional cartoon rendering algorithm based on scan line method, the simulation results show that the new method can overcome the scanning appear abrupt jump and false color stripe and the whole cartoon style is more balanced. It has certain practical application value.
