Red-eye Reduction

APCSP-DYEVJA

Flashes used by cameras will sometimes make people's eyes appear red. Many photo programs on cell phones and computers provide a feature called red-eye reduction. This feature attempts to find the unnaturally red eyes and remove the ​appearance of red eyes from the digital photo.

This is an example of:

A

Computers taking digital information and returning a false information to please its human masters.

B

The internet of things connecting cameras, photos, and databases to create better eyes in the digital photo.

C

Computers using digital information to filter the data and clean up the photo.

D

Metadata on the photos being manipulated and correct by a creative red-seeking algorithm.
