The interaction between machine and human with the development of information technology is growing, and therefore human friendly system is more increasing in actual circumstances. The most important thing in communication between human and machine is the understanding of each other's thought and the knowing of each other's emotion. This paper proposes a new method of grasping human emotion with the emotion recognition through the human's facial image. This new approach consists of two categories, which include the combination of principal component analysis, linear discriminant analysis for pattern recognition problem, and support vector machine for the emotion retrieval from the images.
