Fingerprint is one of the important biometric technologies which have drawn substantial applications now. A fingerprint is the pattern of ridges and valleyson the surface of a fingertip. Ridges and valleys usually run in parallel, sometimes terminate and sometimes bifurcate. At a fine level or local level, the characteristic of ridges and valley are known as minutiae.
Fingerprint ridge density (RD) is defined as the fingerprint ridge count corresponding to a defined fingerprint area. It is determined by two parameters; ridge width and distance between ridges. The fingerprint ridge density has significant sexual dimorphism and has been incessantly reported in multiple populations for forensic applications.
As the world is growing towards digitalization, the working procedures are performing very fast and effectively. The computers have many uses in forensic medicine nowadays. Some software tools are there that need to be installed that gives us the benefit of fast operations especially in the field of fingerprint analysis.
