The conception of AOM (Angle Opening Minimum) and AOM2 methods and the obtained results. a) shows how the shortest distance between all the points of the cornea and one of the sample points of the iris is chosen in the AOM method. The shortest distance for both variants for one analysed pixel is highlighted in bold arrow. b) shows how the shortest distance between all the points of the iris and one of the sample points of the cornea is chosen in the AOM2 method. c) and d) show practically obtained results for all pixels in the implementation of the two variants: the AOM method shown in a) and the AOM2 method shown in b). In order to better visualize the results, the analysis was not limited to the appropriate range of 500 μm.
