【摘要】： 自从计算机的出现开始,人们对计算机图形和动画的研究就没有停止过,尤其是以脸部变形为主题的动漫媒体内容发展迅速。例如,迈克尔·杰克逊的MTV《黑与白》中13个不同性别和种族的人的相互渐变,外科人脸整形手术效果预见,《终结者2：最后审判日》中的T-1000角色能够不断地在液体和金属人和其他角色之间切换,这都得益于图像变形技术的应用。随着计算机、计算等相关学科与技术的不断发展与完善,人脸变形技术的商业价值得到了充分的挖掘,人脸变形在实际工作生活中的应用也必将越来越多。爱美之心人皆有之。本文对一些经典的图像变形算法进行了研究,包括交叉分解、线对特征变形、最小二乘法变形、基于薄板样条的径向基函数变形算法等,详述了各种方法的基本原理及优缺点,并利用MATLAB的GUIDE工具做出一个人脸变形美化的演示系统,实现了对特定的人脸图像进行脸部轮廓、眼睛、鼻子等的美化处理。传统的人脸变形操作主要是将一幅图像渐变到另一幅图像,本文提出了一种新的思想,将传统的人脸变形算法应用于对特定的一幅人脸图像进行美化变形处理。随着生活水平的提高,人们的审美观点相对以前也发生了巨大的变化,本文采用了中国古代的“三庭五眼”的审美标准。经实验验证,本文的人脸变形演示系统在处理有特定缺陷的人脸变形美化能够取得令人满意的效果。
[Abstract]:Since the emergence of computer, people have not stopped the research of computer graphics and animation, especially the animation media content with facial deformation as the theme.For example, in Michael Jackson's MTV, Black and White, 13 people of different genders and races are creeping into each other.It is foreseen that the role T-1000 in Terminator 2: final judgment Day can constantly switch between liquid and metal people and other characters thanks to the application of image deformation technology.With the development and perfection of computer, computing and other related disciplines and technologies, the commercial value of face deformation technology has been fully excavated, and the application of face deformation in practical work and life will be more and more.The love of beauty is common to all.In this paper, some classical image deformation algorithms are studied, including cross decomposition, line pair feature deformation, least square deformation, radial basis function deformation algorithm based on thin plate spline, etc. The basic principles, advantages and disadvantages of these methods are described in detail.A human face deformation and beautification system is developed by using the GUIDE tool of MATLAB, which can beautify the face contour, eyes, nose and so on.The traditional face deformation operation is mainly to gradually change one image to another image. In this paper, a new idea is proposed, which applies the traditional face deformation algorithm to beautify and deform a particular face image.With the improvement of living standard, people's aesthetic viewpoint has changed greatly compared with the past. This article adopts the aesthetic standard of "three courts and five eyes" in ancient China.Experimental results show that the system can achieve satisfactory results in dealing with face deformation and beautification with specific defects.
