IRIS REGISTRATION METHOD AND SYSTEM

A method of compensating for a cyclotorsion of an eye; comprising filtering and unwrapping a pupil-iris and an iris-sclera boundary in a pre-treatment image of an eye; filtering and unwrapping both a pupil-iris and an iris-sclera boundary in a treatment image of the eye; converting the unwrapped ima...

Zusammenfassung:	A method of compensating for a cyclotorsion of an eye; comprising filtering and unwrapping a pupil-iris and an iris-sclera boundary in a pre-treatment image of an eye; filtering and unwrapping both a pupil-iris and an iris-sclera boundary in a treatment image of the eye; converting the unwrapped images from a pixel representation to a feature representation, where each pixel gives rise to one feature vector; measuring a global correlation strength between a feature maps for each possible angle of cyclotorsion; determining an angle that gives the strongest correlation; and aligning a coordinate system based upon the angle.
