 Description: The effective localization of iris position in digital image is the key problem of iris recognition. Using a method based on active contour model to locate the iris location, with a little gray projection method to detect the pupil as the pupil center, the center of a circle as long as it can fall within the pupil. Then, the pseudo center is the center of the pseudo center, and the n-point is taken as the initial snake reference point, and the operation mechanism of snake continues to evolve until the inner boundary of the iris is. Finally, calculate the snake evolution after centroid and the control points and the centroid of the distance on the snake, take the average value as the radius of the pupil, dynamic contour centroid as the center of the pupil of the model, can be accurately pinpoint the location of the iris inner boundary. The experiment shows that compared with the common positioning method, the method is fast and accurate, and the pseudo center of the pupil is not high and the robustness is stronger.
