Most people look at a Magic Eye picture and only see noise.
But hidden inside those repeating dots is a full 3D world, encoded with math.
In this video, we explore the science behind autostereograms:
How a single flat image can store 3D depth
Depth maps, disparity, and binocular vision
The core "trick" that makes the illusion work
Then we go one step further:
if all we have is the final dot pattern, can math reconstruct the hidden shape?
We walk through the key algorithms that decode the illusion:
How correlation and Normalized Cross-Correlation (NCC), finds hidden shifts
How the Fast Fourier Transform (FFT) accelerates the reconstruction
How the recovered disparity map can be lifted into a 3D point cloud
This is a mix of vision science, computer graphics, and signal processing,
all hiding inside an illusion that millions of people still can’t see.
