Line Extraction in Palmprint System

—Today biometric-based systems have been widely used and tipped to replace the traditional methods and one of the emerging techniques is automatic palmprint authentication. To ensure that the matching process achieves an accurate result, the pre-processing of palmprint extraction plays an important role. A new line extraction technique using hysteresis thresholding is presented in this paper. It shows obvious improvement in line feature extraction and provides better base for further matching process.
