Automatic Generation of Caricatures with Multiple Expressions Using Transformative Approach [chapter]

Wen-Hung Liao, Chien-An Lai
2010 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
Introduction The proliferation of digital cameras has changed the way we create and share photos. Novel forms of photo composition and reproduction have surfaced in recent years.  ...  A major strength of our method is that the synthesized caricature bears a higher degree of resemblance to the real person than traditional component-based approaches.  ...

On The Other Side of the Mean: The Perception of Dissimilarity in Human Faces

Volker Blanz, Al.ice J O'toole, Thomas Vetter, Heather A Wild
2000 Perception  
In this space, a caricature can be made by moving a face away from the average face, along the line connecting the particular face to the average face.  ...  This results in a face that is opposite', in a computational sense, to the original face. We morphed several faces into their anti-faces and sampled the morph trajectory in five discrete steps.  ...  surface model).  ...

Interactive 3D caricature from harmonic exaggeration

Thomas Lewiner, Thales Vieira, Dimas Martínez, Adelailson Peixoto, Vinícius Mello, Luiz Velho
2011 Computers & graphics  
A common variant of caricature relies on exaggerating characteristics of a shape that differs from a reference template, usually the distinctive traits of a human portrait.  ...  This lets the user edit the caricature part by part, combining different settings and models of exaggeration, all expressed in terms of harmonic filter.  ...  The social importance and appeal of caricature motivates the investigation of this topic in Computer Graphics.  ...
