摘要 本文给出了一个面向移动数字娱乐的肖像漫画生成系统。该系统的输入是一张真实人脸照片,输出为具有娱乐效果的夸张人脸肖像。主要研究内容包括:第一,人脸照片的肖像插图画的生成。文中采用了Unsharp Mask锐化处理结合色彩缩放运算的方法,本方法不仅考虑到移动设备用户对计算速度的要求,而且能保留人脸的绝大部分特征,从而更为有效地生成人脸的肖像插图画。第二,人脸表情变形以产生人物的幽默漫画。对基于特征的变形方法进行了改进,使其更加自动化。此外,本文改进了传统的ASM方法,用来帮助去除人脸图像背景信息和更为方便地控制人脸上的特征点。整个系统在局域网和PDA上表现出了很好的娱乐效果。 In this paper we propose a caricature generation for mobile digital entertainments device. The input of system is a facial photograph, the output is entertaining caricature. The main research work include: first, we create illustration from photographs of human faces. We apply Unsharp Mask sharpening and scale color processing. It's not only considering the speed of mobile device, but also reserving many facial features. These studies show that the facial illustrations generated using our techniques produce images that are effective. Second, generate the caricatures by image morphing. We improve the traditional feature-based metamorphosis for automation morphing. In addition, we improve the traditional ASM method for removing the background of facial photographs and controlling facial feature points. The system presents better entertainments.
