New Stereo Pair technique

Sample image for Parallel vision method. I had an idea, how to create stareo pair images from 2D data by using real 3D software. First the grayscale image, with suppressed stars, is turned to hight map by using shades of gray as an indicator. Based on this model I created 3D mesh. Original image with color information is then projected to this surface. After that I'm able to take images from this object with small angular difference. Now I have two images and needed spatial information. An other new innovation was to use several iterations of "minimum" command under PhotoShop to select stars with different brightnes. now it's easy to manipulate star distance accuratetly.
Sample image for Cross Vision method PARALLEL VISION ISTRUCTIONS: In parallel freeviewing the image for the left eye is on the left and the image for the right eye is on the right. You stare into the screen so that your eyes are aimed (more or less) parallel. As you stare into the screen you will get double vision as each eye sees the L & R images separately. When you are staring in at the right distance the middle two images will overlap and become 3d. The outer two images will remain and will still be 2d.

CROSS VISION INSTRUCTIONS: In cross eye freeviewing the image for the left eye is on the right and the image for the right eye is on the left. You stare at a point about 1/2 way to the screen so that your eye's gaze is crossing at the half way point. Thus the left eye sees the correct image which is on the right. As you cross your eyes the image will go double. When your eyes are crossed the correct amount the middle images will overlap and be in 3d. The two outer images will remain and will be in 2d.
