. To see a Magic Eye image, you must use (diverging your eyes so they focus behind the paper).

: Because our eyes are separated horizontally by about

While traditional 3D media (like polarized cinema glasses) force the left and right eyes to see separate images, an autostereogram cleverly encodes both perspectives into a single repeating 2D image. 2. Historical Background

: If viewing on a monitor, try to look at your own reflection on the screen glass. This automatically sets your eyes' convergence point behind the actual physical screen, allowing the stereogram to pop out in your peripheral vision. 6. Conclusion

: The visual cortex calculates the disparities between these two flat retinal images to compute depth and construct a spatial understanding of our surroundings.

Iterate through the image from left to right. For each pixel at position , calculate its required shift based on the depth map value. You then force the color at to be identical to the color at Step 4: Smooth the Output Because a pixel at position
