| Summary: | 碩士 === 國立交通大學 === 多媒體工程研究所 === 98 === In this thesis, we propose a two-stage method to simulate the aging process of a human face. We use EM-like algorithm and PCA-based data filling method to estimate the geometric and facial texture variation of a target face from subspace of aging patterns. Since the facial texture predicted by PCA-based method cannot preserve personalized details, we propose using a superimposing method. We establish a facial texture database with high resolution pictures, and synthesis the detailed wrinkles or creases by texture synthesis. Besides, we further analyze the parents' inheritable impact in the aging simulation. Our experiments show that the proposed example-based method is able to provide reasonable simulation of face aging.
