Spectral Graph Wavelet Theory with Statistical Features for Face Recognition

Spectral Graph Wavelet Theory(SGWT) is one of the modern techniques in imaging science and is used for face recognition in this project.Spectral Graph Wavelet Theoryimplements an efficient approach for automatic face recognition.Like wavelet transform SGWT is defined atthe arbitrary finite weighted graph vertices and the transform functions are defined on the weighted graph vertices.At first the SGWT decay the given face image.The obtained sub-band energies are combined together and the corresponding image is considered as feature vector.Using nearest neighbor classifier,face images in the ORL database is analyzed in the proposed system.The input face image hasposevariations, and also variation in expression and face details,which is used in this study.Thus the proposed system based on Spectral Graph Wavelet Theory produced better result and achieved 96% of recognition accuracy
