Abstract: A head image registration uses a plurality of combined 2D and depth images, for example RGBD images, of a head recorded from different positions. Landmark points are determined for each of the combined images. The registration is performed as a coarse registration based on the landmark points followed by a fine registration based on full point clouds. Based on the registration, a head model may be generated.

Abstract: Concentric ring electrodes in a conventional electro-active lens are arranged in the same layer and spaced apart from each other to prevent electrical shorts. The spacing between electrodes depends on the substrate material and how the electrodes are made. Ideally, the electrodes should be as close together as possible to prevent eddies or discontinuities in the electric field that the electrodes apply to the electro-active material in the electro-active lens. These eddies or discontinuities degrade the electro-active lens's optical quality. Unfortunately, current photolithographic patterning processes cannot produce gaps smaller than about 5 microns on plastic substrates. To compensate for this constraint, the electrodes can be arranged on the substrate in two or more staggered layers, with the electrodes in one layer appearing to fill the gaps in the other layer(s) when looking through the electro-active lens.
