Modification Technique of 3D Facial Models for Improving Beauty

People usually try to show themselves attractively, since attractive looks are generally preferred. We propose a new method for modifying facial data in order to improve facial beauty while retaining the original features as much as possible. Based on investigations into related work of facial attractiveness, the targets for modification in our method are small and/or unbalanced eyes, and a projecting mouth. We apply these modifications to 3D facial data sets. The data sets have the characteristic points that are classified into facial parts. The coordinates of the characteristic points are moved, the modification affects the raw data points surrounding the characteristic points, and a modified face is represented. We evaluated the modified faces of eight people with a questionnaire survey. As a result, we confirmed our method was useful for increasing the beauty of facial data while retaining the original features as much as possible.
