| Abstract: | Feature extraction is an important process in palm-print identification.This paper proposed a novel feature coding method.Having located 1D signal of finger and 2D region on palm,wavelet zero-crossing and Gabor filter are used to extract feature used in identification,respectively.And the experimental result of 96.2% correct ratio demonstrates the effectiveness of the proposed method done on captured palm database. |
