Abstract
An automatic feature extraction system for analyzing a face image and finding the facial features of the face. In the pre-processing stage, a second-chance region growing method is applied to determine a face region on the face image. In the feature extraction stage, three primary facial features, including both eyes and the mouth, are extracted first. Then other facial features can be extracted according to these extracted primary facial features. Searching feature points can be achieved by calculating the cost function of each point using a simple feature template. In addition, a genetic algorithm can be used to accelerate the process of searching feature points.
