Fingerprint image super resolution using sparse representation with ridge pattern prior by classification coupled dictionaries.
IET Biometrics(2017)
摘要
A new algorithm for reconstructing the fingerprint super-resolution (SR) image is presented. The basic idea of the algorithm is to reconstruct the SR image by using sparse representation with ridge pattern prior based on classification coupled dictionaries. First, the orientations of training patches are estimated by the weighted linear projection analysis. In the second procedure, the qualities o...
