Abstract
A iris recognition system based on DSP is designed in this paper. A fast algorithm designed in this system for iris feature recognition. First, a point is given within the pupil randomly, and then calculate the radius from the edge detection. So the edge of pupil is drawn out. The same method is applied to find the edges of the iris. After fitting the edge, a cylindrical is drawn. The pretreatment of normalization and feature extraction is carried out using this arithmetic. This algorithm is simulated in Matlab. The results show that this algorithm is effective. In the end through program, this algorithm is run in the DSP. The run result shows it is efficient and stable.
