Title: A virtual sculpture based morphable face model
Author: Riewe, Jessica Lauren
Abstract: Exemplar virtual three -dimensional sculptures collected from sixteen artists are used to develop a multidimensional space to describe facial shape , which is then used as a mechanism for modeling new faces . This is accomplished through identifying and varying derived principal components of the multi -dimensional space . The relationships between these principal components and their effects on new faces are explored through the creation of new virtual faces using a graphical user interface . These new virtual face sculptures are then modified by facial feature , gender , and expression using a feature -based transformation interface based on difference vectors . Finally , animations are created to illustrate the results of these approaches . Facial mesh transformations based on principal components does not give direct predictable control for modifying specific facial features . However , it does provide interesting design choices for artists , and general patterns of the data variance were obtained . The feature -based transformations were successful in further modifying created faces .
