Abstract：
 The invention discloses a method of two-dimensional face image recognition, pertaining to the field of pattern recognition and computer vision. The method includes that: building a three-dimensional face deformation model according to the known three-dimensional face database; inputting a two-dimensional face image to register, and rebuilding in three dimension the registered two-dimensional face image using the three-dimensional face deformation model to obtain the three-dimensional rebuilt result of the registered two-dimensional face image; by constructing an illumination model, generating a virtual image with the changing posture and illumination in the three-dimensional rebuilt result; designing a change limitation classifier using the virtual image; inputting the two-dimensional face image to be recognized, implementing feature extraction and compression processing, then inputting the features processed by extraction and compression processing to the change limitation classifier, outputting the classified result, and finally realizing the face image recognition. The method in the invention realizes the full automation of the recognition procedure, enhances the recognition accuracy, and largely improves the recognition speed.
