Abstract :
We propose a ridge detection method for palm print identification using low-resolution images. Before the image processing such as Hough transform, we focused on extracting the exact principle line of palm print using contours. To solve the LF (local flatness) problem on the image, we used the DAROC (downhill along the ridges on the contours) algorithm utilizing distance, angle and momentum.
