1. A method for determining positions of eyes of a face in a two-dimensional digital image, spatial dimensions of the two-dimensional digital image consisting of a first spatial dimension and a second spatial dimension, the first spatial dimension being orthogonal to the second spatial dimension, the method comprising: determining a pair of approximate positions of the eyes in the two-dimensional digital image; determining test pairs of the positions of the eyes on a basis of the pair of approximate positions, each position of an eye in each of the test pairs being in an adjacent area of the approximate position of a corresponding eye; geometrically transforming, for each test pair, the two-dimensional digital image into a normalized image in such a way as to make the positions of the eyes of each test pair coincide with a pair of predetermined reference positions; comparing at least a part of each normalized image covering at least a part of the face with a corresponding part of a predetermined image, each comparison providing a score representing a level of resemblance between the part of the normalized image and that of the predetermined image; and declaring the positions of the eyes of the test pair associated with the best score as actual positions of the eyes of the face.
