摘要：

In　this　paper,　a　3-channel　wavelet　transform　method　is　introduced　to　recover　palm　print　images　following　serious　deformation.　The　deformation　processing　is　actually　a　kind　of　digital　re-sampling.　A　filter　bank　consisting　of　three　filters　is　implemented　for　wavelet　decomposition　of　the　palm　print　image,　and　then　a　procedure　of　binary　interpolation　is　performed　after　the　image　is　reconstructed　by　another　filter　bank　consisting　of　another　three　filters.　The　design　of　multi-channel　wavelet　filter　bank　is　based　on　the　Quadrature　Mirror　Filter　(QMF)　method.　Because　the　noise　is　caused　by　the　Morie　stripe,　the　images　are　further　de-noised　after　the　geometry　deformation　is　addressed.　Acceptable　results　have　been　obtained.　©　2006　Informa　UK　Ltd.
