Iris is the part of the eye that can expand and shrink depending on the intensity of light entering the eye.Iris can be used as a feature or parameter that can be studied in terms of both health and information technology.Detecting the iris in this paper, are separated into two main stages: preprocessing stage and iris detection stage which uses circular Hough transformation (CHT) algorithm), on the preprocessing image frame, the captured image will be cropped first, using ROI(region of interest) then grayscalling will take place on detection in edge detection with Canny operator, this is done in order to optimize circular Hough transformation (CHT) algorithm application in detection of iris, then in the second phase it will implement the results of applying the circular Hough transformation (CHT) algorithm with and without the OpenCV library.
