Abstract
A method of compensating for distortion, in a plurality of retinal image frames, arising from eye movement receives at least one reference image frame and plural other image frames of the eye. For each frame, the method determines a plurality of shifts relative to the reference image frame, and an initial eye movement trajectory based on at least an initial reference frame distortion, and the shifts within each of said other image frames. The method estimates a current reference frame distortion using the initial trajectory and the shifts within each of the other image frames, and a current eye movement trajectory based on the estimated current reference frame distortion, and the shifts within each of said other image frames to provide a smooth transition between the other image frames in the eye movement. With this the method compensates for distortion in said frames using the current eye movement trajectory.
