Age Manipulation of Facial Images Focused on Spots and Wrinkles

Abstract

Extensive studies have been done on manipulating individual facial attributes, such as expression and age, to synthesize facial images. Most studies have focused on manipulation of the shapes of facial parts, such as eyes, mouths, or outlines, but spots and wrinkles have been treated as simple global features, such as skin color and texture. This research, on the other hand, analyses the shapes of individual spots and wrinkles for their extraction and manipulation. Extraction and classification of the wrinkles and spots are based on the characteristics of pixel distribution within each spot pr wrinkle, not on its contour shape. We conducted human evaluation experiments, confirming that manipulating spots, wrinkles, and facial parts altogether more effectively manipulates age than manipulating only facial parts.
