Daughmans algorithm

Web1) The word iris is derived from the Greek goddess of the rainbow, due to the many colours of the iris. 2) Definition: “The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupils and thus the amount of light reaching the retina.”. WebDaugman proposed to detect the inner and outer iris boundaries using an active contour method, based on the discrete Fourier series expan- sion of the contour data [1]. Shah and Ross combined snake segmentation with geometric active contours [20].
