Prototyping and transforming facial textures for perception research - Computer Graphics and Applications, IEEE

ceived dimensions (such as age, gender, race, or health) has application in areas as diverse as psychology, medicine, and forensics. We can use prototype images to define the salient features of a particular face classification (for example, European female adult or EastAsian male child). We then use the differences between two prototypes to define an axis of transformation, such as younger to older. By applying these changes to a given input face, we can change its apparent age, race, or gender. Psychological investigations reveal a limitation with existing methods that’s particularly apparent when changing the age of faces. We relate the problem to the loss of facial textures (such as stubble and wrinkles) in the prototypes due to the blending process. In this article, we review the existing face prototyping and transformation methods and present a new, wavelet-based method for prototyping and transforming facial textures.
