TLDR
Experimental results for impression transformations of both age and gender dimensions showed that the method proposed for face image manipulation is an effective one.Abstract:
This work describes an attempt to develop a real-life application for transforming the appearance of a person's face to give a more favorable impression. Face images are first represented as high-dimensional vectors by separating the shape and texture information, and variations in the appearance of face images are coded by applying principal component analysis to a set of various face images. The relationship between the coded representation and the impression of corresponding images is analyzed, and an impression transfer vector is defined by the Fisher's linear discriminant obtained from a number of training images previously categorized into two opposing classes for a given impression dimension. An image manipulation method for transforming impressions is proposed which shifts the projection of the input image in the parameter space by an arbitrary magnitude of the impression transfer vector. Experimental results for impression transformations of both age and gender dimensions showed that the method proposed for face image manipulation is an effective one.read more

Estimating aging pattern by aging increment distribution for re-rendering of facial age effects
TL;DR: A novel aging model called Aging Increment Distribution Function was proposed to model the age progression in the statistical appearance model space that has finer resolution to reveal the underlying aging pattern.

Automatic impression transformation of faces in 3D shape - a perceptual comparison with processing on 2D images
TL;DR: In this article, an attempt to transform a 3D model of a person's face to produce an intended change of impression is described, where 3D shape and surface texture of faces were represented by high-dimensional vectors automatically extracted from the 3D data captured by a range finder, and variations among a set of faces are coded by applying principal component analysis.

Effects of sexual dimorphism on facial attractiveness

TL;DR: The results of asking subjects to choose the most attractive faces from continua that enhanced or diminished differences between the average shape of female and male faces indicate a selection pressure that limits sexual dimorphism and encourages neoteny in humans.

TL;DR: In this paper, the effects of aging on facial appearance can be explained using learned age transformations and present experimental results to show that reasonably accurate estimates of age can be made for unseen images.

TL;DR: Computer vision researchers are developing new approaches to object recognition and detection that are based almost directly on images and avoid the use of intermediate three-dimensional models.

Perceptual information for the age level of faces as a higher order invariant of growth.
TL;DR: Because cardioidal strain produces changes in structures that do not share an isomorphism of rigid (Euclidian) local features or rigid feature configurations, this transformation seems both sufficiently general and abstract to specify what J.J. Gibson has called a "higher-order invariant of perceptual information".
