Abstract
The basic iris location algorithm based on Hough transform is reviewed, and several problems involved in implementing the algorithm are discussed. A two-step coarse-to-fine approach is used to reduce the time and space complexity. The relation between inner and outer edge of iris is exploited to (reduce) the influence of noise. Experiments under MATLAB prove the effectiveness and efficiency of the (algorithm.)
