Binary Vision refers to images or movies with no color and no continuous tone. Important aspects of human vision are known to be binary. Binary images are sometimes called "undithered" ,"bilevel", or even the "raw primal sketch".

Binary images have long been popular in text, pattern recognition, and machine vision. Recent technology now allows Binary images, for the first time, to also do a first rate job with natural images, including images of the human face.

Modern software for producing Binary images from Color or Grayscale images comprises hundreds of millions of complex, patented, computer instructions. The software is automatic, extremely simple to use, and is completed in near realtime on current generation microprocessors.

Binary images can be printed and displayed on many devices that can't process Color or Grayscale images. Binary images are also easier, faster, and less expensive to copy, fax, and transmit. Also, in the U.S. an estimated 2,000,000 people struggle with Low Vision. Often a Binary image can be recognized by a person with Low Vision, while Color or Grayscale just look like mud.
