DISTORTED PATTERN RECOGNITION

DISTORTED PATTERN RECOGNITION

Humans have a much stronger ability to recognize patterns, especially when they are familiar with them. Colin Ware writes: V4 neurons still respond strongly to patterns despite distortions that stretch or rotate the pattern [...] (Visual Thinking for Design, Colin Ware, P.57).

An example in our daily life is the CAPTCHA (Computer Aided Public Turing test to tell Humans and Computers Apart). It is a method to assure that a human, in contrary to a computer, is giving the response. Captchas are distorted pieces of text, sometimes combined with angled lines, generated by a computer. A person then has to decipher the text in the distorted image and give the right answer.
