Hand Geometry Recognition System : Discover the Simple and Hypride Source Code for Hand Geometry Recognition System. Hand Geometry-based Biometric Recognition systems are gaining acknowledgement in security applications, ranging from low to medium level. Hand Geometry-based identification systems make use of geometric features of the hand like; length and width of the fingers, diameter and perimeter of the palm, etc. The proposed algorithm is a verification technique, which exploits these hand geometry features for user authentication. The Hand Geometry Recognition System accepts the input grayscale handprint from which it extracts information such as; the length of the fingers, widths and perimeter of the fingers, etc. The system is estimated to be 95% accurate.
