But when you see both images, you can say what is the hidden image — stereopsis occurs somewhere in the brain.You can say more: it is somewhere in the brain that receives information from both eyes.

One group (NV) was given either no information or just verbal information about the shape of the embedded object.A second group (group VV) received both verbal information and visual information (e.g., a drawing of the object). The theory behind RDS has wide implications in cognitive and neuro sciences.The name 'random dot stereogram' (RDS) is now often used instead of 'single-image random dot stereogram' (SIRDS) or 'random dot autostereogram' in publications such as s, on the other hand, uses repeating patterns on a single image to eliminate the need for pair of images.Creating a Random Dot Stereogram The first step is to create a random dot Copy the image side by side: Select a small region of one Shift (horizontally only) this small region: The Random Dot Stereogram is ready: Cognitive and Neuro Sciences Autostereogram is important because it made the concept of a random dot stereogram widely public for non-scientific people. It has an axiom: random dots do not convey any kind of three dimensional information (shape from shading, contours, etc).It happened because it is a very interesting illusion. If you present only one image, you can't say what is the hidden image (it is only random dots, see axiom).
