人脸识别软件仅仅单独采用一种现有的人脸识别方法一般都不会取得很好的识别效果。各种技术和方法都有自己不同的适应环境和各自的特点。如果我们想进一步提高人脸识别系统的识别率，可以考虑使用数据融合理论，将不同的方法综合起来，相互补充，来取得很好的人脸识别效果。这也是为人脸识别的研究趋势之一。-Only uses a single conventional face recognition methods are generally not made good recognition. Various technologies and techniques have their own different adapt to the environment and their own characteristics. If we want to further improve the recognition rate of face recognition system, consider using data fusion theory, different methods together, complement each other to obtain good recognition results. This is also one of the research trends in face recognition.
