Lei Tang, Xian Wei Li · Advanced materials research · 2013
Wavelet transform is of vital importance in face recognition. This paper studies key problems of wavelet transform of face recognition and analyzes some problems that affect on face recognition rate. Experiments are done based on the same face images using different decomposition levels and different DB. Experiments show that recognition rates can get better results when using DB2 and the decomposition level two.
