hi Mr.Dave,
               we are students, we r doin age estimation project We have done face
 detection,face normalization.how to perform wavelet transform to  facial regions images(which transform eg fourier  can you help with function names.?how 2 extract 
wrinkles ???
                      thanx in advance
