The paper presents a method of pupil and iris boundaries determining on eye images.The aim is to find out the parameters of approximating circles, namely, the coordinates of centers and radiuses.To solve the problem, several steps are implemented: morphological processing and a binarization of the input image, determining the pupil parameters, detecting the image edges with the Canny edge detector, and determining the iris parameters using a density of a points distribution by these distances to the just found pupil center.The mixture of the 2331 different iris images is used to test the algorithm.
