New version of C code for iris segmentation module

Biometric systems are developed to verily and-or identify persons, for access control, identification systems or border management. They are based on the unique biological characteristics of persons like face, finger, iris, hand, signature, voice. In comparing with other biometric technologies, the iris recognition system has very high recognition accuracy. This system consists of several stages including segmentation stage which is the most important and critical one. In this paper, we present an amiliored version of C code for iris segmentation module. Which is based on the OSIRIS System, coded in C++ language, and had OpenCV library functions. In order to have a new algorithm independent to the OpenCV library, and added the pre-processing module to improve the performance of the OSIRIS system. The system acquires the eyes data from the ICE 2005 data base. This algorithm has a good precision, more than 94. %.
