    • 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.
    • 一种自动特征提取系统,用于分析面部图像并找到面部的面部特征。 在预处理阶段,应用第二机会区域生长方法来确定面部图像上的面部区域。 在特征提取阶段,首先提取包括眼睛和嘴巴在内的三个主要面部特征。 然后可以根据这些提取的主要面部特征提取其他面部特征。 通过使用简单的特征模板计算每个点的成本函数可以获得搜索特征点。 另外,遗传算法可以用来加快搜索特征点的过程。
