This document discusses stereograms and stereo vision for 3D displays. It explains that stereograms use slightly different left and right images to create the perception of 3D when viewed through special glasses. There are three main types of 3D displays: polarization, anaglyph (red-blue glasses), and 3D goggles. The document also briefly covers computer vision techniques for 3D reconstruction from images and invites the reader to experience 3D videos online through side-by-side viewing formats.
