Several tests widely used in research or the clinic are based on this technique. CC-BY-SA-3.0 Creative Commons Attribution-Share Alike 3. The random-dot stereogram is the most used method of evaluating stereoacuity. In experiment 1 the retinal position-specific learning effect was reproduced and in a follow-up experiment it was shown that the position specificity of learning can be accounted for by selective visual attention. This licensing tag was added to this file as part of the GFDL licensing update. In the present study some specific properties of the learning effects reported for random-dot stereograms are examined.

A red blue random dot stereogram written in Python for my Introduction to Perception class. It uses this repeat interval to look up the color of the counterpart pixel to the left and uses its color as the new pixel's own color.I, the copyright holder of this work, hereby publish it under the following licenses: For every pixel, it subtracts the shift from the width of the pattern image to arrive at a repeat interval. Binocular depth perception, or stereopsis, depends on matching corresponding points in two images taken from two vantage points. You may watch the two dots at the top of the page become four. Allow your eyes to space out and gaze through the paper. Seeing the 3-D image is a fun way to achieve PhotoFocus, the divergent gaze used for PhotoReading. Then it consults the depth map to retrieve appropriate shift values for subsequent pixels. Imbedded in the computer generated 'random dot matrix' below is the 3-D image of the word: PHOTOREAD.

It seeds the first series of pixels in a row from the pattern image. One way to accomplish this is to make the program scan every line in the output image pixel-by-pixel from left to right. Conceptually, at every pixel in the output image, the program looks up the grayscale value of the equivalent pixel in the depth map image, and uses this value to determine the amount of horizontal shift required for the pixel. The program tiles the pattern image horizontally to cover an area whose size is identical to the depth map. The wikipedia article on autostereograms describes the algorithm for creating depth map based stereograms like this:Ī computer program can take a depth map and an accompanying pattern image to produce an autostereogram.
