Abstract
This paper proposes the use of the phase congruency to enhance the palmprint image used for palmprint identification. By using phase congruency, the palmprint lines which act like the edges in the palmprint image are detected. The resulting phase image is shown as the enhanced palmprint image. Comparing with the previous palmprint enhancement method that uses the phase symmetry proposed by Kovesi et al. (1997), the proposed method is significantly less sensitive to the textures which are not the palmprint lines in the palmprint image. © 2008 IEEE.
