Video: Chessboard illusion confuses people's ability to recognize colors

The illusion of a chessboard shadow was discovered by MIT professor Edward H. Adelson and performed by the YouTube account brusspup.

This interesting illusion is designed to be very simple, consisting only of a chess board with 2 light-colored squares - dark and light and a large object blocking the light of the chessboard. Initially, we will not understand the special feature of this illusion until the creator reveals the unexpected truth behind. Turns out, two colored squares that seem to be in contrast actually have the same color.

This chessboard illusion exploited the mechanism of action of the human eye to deceive the way we perceive images.

In fact, the owner of the chessboard used gray boxes with different weights. When illuminated, the shadow of the obstruction will make the color of the color cells darker. Together with the contrasting shades, it makes it impossible for our brain to realize that bright and shadowed cells and dark areas in the light actually have the same color tone.

 

This chessboard illusion exploited the mode of operation of the human eye to deceive us: First, the eyeball receives two-dimensional images, then the brain analyzes and estimates the surrounding environment (correlated length , brightness .) then convert it to a 3-dimensional image.
