This paper studied the simulation problems of facial aging with the computer visual processing software. According to comparing the most used facial pictures, this paper decided to take the face images from FE-NET database as the objects of modeling analysis. Considering the AAM, WT and other Facial Feature Extraction Algorithms, this took the AMM algorithm to extract and mark the facial feature, gray and match histogram. Actually, the high dimensionality of the extracted feature has a bad affection on efficiency and result in post processing, so this paper adopts the classical method PCA to process the facial feature set. This paper adopts a piecewise-linear algorithm to segment all facial images based on ages to four sections, and extract features of every section to make linear similarity compare. This paper simulates images and reverse simulation in every section, with good results.
