Facial perception research has benefited from the use of computer graphic methods, such as facial image prototyping and transformation. This paper describes new methods for improved prototyping and transformation of skin textures including wrinkles and stubble. We use a biologically inspired wavelet transform to capture the textural detail in different… (More)
A n e w general solution for the construction of one-to-one image warping functions is presented. The algorithm takes a set of user speciied translations and constructs a set of one-to-one warps by interpolation and scaling. These are concatenated to produce a single one-to-one warping function, which prevents overlap in the resultant w arped image.
Facial feature tracking is crucial in computer vision applications. In this paper, we propose a system capable of locating a human face using skin color filtering and then detecting and tracking six facial features, i.e. pupils, nostrils and lip corners, in a real time video. A 3D facial feature model is employed to estimate the 3D pose of a person's head,… (More)
This paper describes a new method for creating visually realistic moving facial image sequences that retain an actor's personality (individuality, expression and characteristic movements) while altering the facial appearance along a certain specified facial dimension. We combine two existing technologies, facial feature tracking and facial image… (More)
Sexual reproduction strategies vary both between and within species in the level of investment in offspring. Life-history theories suggest that the rate of sexual maturation is critically linked to reproductive strategy, with high investment being associated with few offspring and delayed maturation. For humans, age of puberty and age of first sex are two… (More)
Animated talking faces can be generated from a set of predefined face and mouth shapes (visemes) by either concatenation or morphing. Each facial image corresponds to one or more phonemes, which are generated in synchrony with the visual changes. Existing implementations require a full set of facial visemes to be captured or created by an artist before the… (More)
