The invention, exemplified as a single lens stereo optics design with a stepped mirror system for tracking the eye, isolates landmark features in the separate images, locates the pupil in the eye, matches landmarks to a template centered on the pupil, mathematically traces refracted rays back from the matched image points through the cornea to the inner structure, and locates these structures from the intersection of the rays for the separate stereo views. Having located in this way structures of the eye in the coordinate system of the optical unit, the invention computes the optical axes and from that the line of sight and the torsion roll in vision. Along with providing a wider field of view, this invention has an additional advantage since the stereo images tend to be offset from each other and for this reason the reconstructed pupil is more accurately aligned and centered.

An image processor generates a Super-Resolution (SR) frame by upscaling. A Human Visual Preference Model (HVPM) helps detect random texture regions, where visual artifacts and errors are tolerated to allow for more image details, and immaculate regions having flat areas, corners, or regular structures, where details may be sacrificed to prevent annoying visual artifacts that seem to stand out more. A regularity or isotropic measurement is generated for each input pixel. More regular and less anisotropic regions are mapped as immaculate regions. Higher weights for blurring, smoothing, or blending from a single frame source are assigned for immaculate regions to reduce the likelihood of generated artifacts. In the random texture regions, multiple frames are used as sources for blending, and sharpening is increased to enhance details, but more artifacts are likely. These artifacts are more easily tolerated by humans in the random texture regions than in the regular-structure immaculate regions.
