摘要： A method and an apparatus for constructing classifiers based on face texture information and a method and an apparatus for recognizing a face using statistical features of texture information. The method of constructing classifiers based on face texture information includes: cropping a first face image and a second face image from two different images; dividing the first face image and the second face image into partial images of predetermined sizes and cropping first partial images corresponding to the first image and second partial images corresponding to the second image; extracting first texture information corresponding to texture information of each of the first partial images and second texture information corresponding to texture information of each of the second partial images; checking similarities between the texture information of partial images of the first face image and that of the corresponding partial images of the second face image; and constructing weak classifiers for recognizing an identity of the face based on partial images according to the checked similarities.

摘要： A face recognition method and apparatus using extended Gabor wavelet features are provided. In the face recognition method, extended Gabor wavelet features are extracted from a face image by applying an extended Gabor wavelet filter, a Gabor wavelet feature set is selected by performing a supervised learning process on the extended Gabor wavelet features, and the selected Gabor wavelet feature set is used for face recognition. Accordingly, it is possible to solve problems of a high error rate of face recognition and low face recognition efficiency caused from a limitation of parameters of the Gabor wavelet filter. In addition, it is possible to solve the problem of increased calculation complexity caused from using an extended Gabor wavelet filter and to implement robust face recognition which is excellent in dealing with a change in expression and illumination.
