    Specialized cells in the eye work in parallel for unequaled image processing and computation. Millionfold swings in light intensity from the outside world, transformed to electrical signals, are processed in space and time for contrast and edge enhancement, as well as to detect motion.

    Analog circuits based on resistive networks emulate the behavior of the vertebrate eye, detecting edges, differentiating between surfaces, and estimating motion. The speed and simplicity of these devices make them candidates for applications ranging from security systems to retinal replacements. View full abstract»

    Arrays of stimulating electrodes can be placed in the brain itself, in the visual cortex, to bring vision to the profoundly blind. However, when designing such devices one needs to take into consideration the fact that the visual pathway maps images onto cortical structures in a complex and unpredictable way.

    The mind cannot make sense of the visual world out of raw image data alone. In an approach to visual processing known as learning from examples, computational neural networks and physiological studies suggest how neurons and machines adapt to novel images on the basis of past experience.

    As the second millennium draws to a close, huge numbers of computer programs will begin belching and hiccupping because they cannot properly process dates beyond Dec. 31, 1999. The years from 2000 on start over at 00, and unless something is done, these dates will appear to precede the 1900s—or so it will seem to the many programs that use only a year's last two digits for dates.
