Anatomically, the human eye is like a sophisticated tentacle that reaches out from the brain, with the retina acting as the tentacle’s tip and touching everything the person sees. Evolution worked a wonder with this complex nervous structure.
Now, contrast the eye’s anatomy to the engineering of the most widely used machine-vision systems today: a charge-coupled device (CCD) or a CMOS imaging chip, each of which consists of a grid of pixels. The eye is orders of magnitude more efficient than these…
