Iris Recognition Using Visible Wavelength Light Source and Near Infrared Light Source Image Database: A Short Survey□

In most of the iris identification systems, the complete image constraints are understood. These Constrain include near-infrared (NIR) illumination to release the iris texture and close distance from the capturing device. In recent advances to different illumination technologies introduced in images captured in the environment. This environment includes a visible wavelength (VW) light source at-a-distance over the close distance from the capturing device. For accurate Iris identification at-a-distance, eye images require improvement of effective strategies. By using implementation of iris-identification-at-a-distance (IAAD) systems. For feature extraction technique for NIR and VW images were taken under uncontrolled environment. For the identification of iris accuracy on the publicly available databases proposed in comparison to the contemporary.
