The two new methods for locating the outer edge of iris were presented by researching of iris images. The first is to locate the inner edge of iris by using canny operator and Hough transform method. The selection of the appropriate threshold is based on the diagram which observes the color distribution of the iris image; the second is that the circle integral and linear segment methods to locate the outer edge of iris are presented. We would like to indicate that the experiment results show that both of the two methods have the following qualities: rapidity, availability, real time calculations and accuracy in locating the iris outer edge.
