1. A computer-implemented method comprising: obtaining an eye image; determining, using one or more processors, a horizontal displacement between a center of an iris and a center of a pupil in the eye image; generating an initial prediction of an eye type based on the determined horizontal displacement, the initial prediction comprising (i) a prediction of a biological right eye image in response to the determined horizontal displacement indicating a positive pixel distance space, or (ii) a prediction of a biological left eye image in response to the determined horizontal displacement indicating a negative pixel distance space; obtaining data identifying at least one of an inner eye corner and an outer eye corner in the eye image; and determining that the eye image is a left eye or right eye based on the initial prediction and the data identifying the at least one of the inner eye corner and the outer eye corner.
