View Full Version : Cool optical "illusion" basis for 3D without special glasses

Thought u may enjoy seeing some of the older technology - how it is being created today to allow for 2D images, (flat screen images) to be converted into fake but brain believable..

Making 3D releases of the older feature length films is a great "new" (ah hum..) Hollywood industry.

Some companies are claiming they have techniques that can produce viewable screens that don't need glasses.

For this pix, one needs to do a bit of a cross eyed view to "see the image".

If you have a laptop (on the lap for the viewing distance), move your thumb to about two hand widths infront of your nose. (now remove your thumb out of your field of view) Glance at the computer screen without changing your focus (to where ur thumb was)

The object is is to merge the two pictures in your vision so that there is a third image formed in the middle of the two.. See what you see in the middle image. There should be depth and a 3D like effect.

This technique is usable with NOISE-LIKE images (intensity modulation in grey noise or color noise) to simply create the effect - (I may post a few of those later).

This technique lends itself to be used with stills, animations, movies, films and videos to lay in a hidden series of messages.. The brain inputs the data without conscious knowledge..

METHOD:
The technique uses an "optical contrast separation" to split the two images to provide 3D depth, in other words optical filtering, the image you are looking at on the screen (when there is a hidden message in it) contains the two split images on your peripheral vision.

When one watches an encoded video intently, if there is a hidden message there, the 3D version is imparted directly into the brain. The magic that is part of the process is called "the CornSweet Illusion" (see wiki) - this was discovered and talked about publicly in the 60's.

This image creation method for the subliminal program becomes a LAYER in the video frames.

- the video "normal content" without message is on one layer for the video mixing, and the "message layer" is setup (with two images on the left and right) in the other mixing layer.

The intensity of the mix is chosen to be relatively optically un-noticable.

The object is to duplicate the placement of the "message" image layer to be on the left and right sides (or top and bottom), of the normal optical center (one looks at the center of the image usually while watching, ignoring the edges..

Brain re-assembly happens as is shown in the pis below.

It is the perfect way that MK Ultra types would be able to implant the masses, using social media current tools.. a perfect way to "spread the message". Notice in the demo a reptile dragon is used for the illustration..

It can be done simply with color "noise" to remain a bit "grainy" in appearance to see like a poorer quality movie, poor equipment and so forth.

More exotic methods can use this technique by putting a selective filter on the existing live normal image creating "contrast holes" in either chroma (color) or luminence (black and white brightness levels) - in other words a subtractive NEGATIVE image. Either works.

This particular image set is designed to allow for the red green image modulation to also impart "depth" and trigger brain synthesis of images. (the left image uses the RG additional colors..

Do I watch social media videos, no way.. since I've known about this years and years ago when video editing was first coming out.. I''ve told folks about this, but they say "WATCH THE VIDEO BOB !" This technique is old, surprising folks haven't talked about it in how it can be used for "programming" social media.. Folks stay away from mainstream TV, but gladly watch social media movies.. :) I think that is humorous.

There's more but this will get you started to "see" how it is done.

Very interesting! I even have the feeling/illusion that the dragon images on the left are in movement.

Bob: I copied the dragon images into Photoshop and removed the color elements from the left image (turned both images into black and white) and when the two images merged, there was still the 3D effect. I'm not understanding the significance of the color, since the two separate images are already different enough without color added to create a 3D effect. I'm fascinated by subliminals and would like to learn about what you know in greater depth.

Hi NoneSuch :)

The addition of the red green in the left image was to allow for what is called a backward compatibility with the red-green 3D glasses method of using color compliments to create a sensation of depth..

The information modulation in the two images though, the black and white uses an ability of side-by-side bright.dark modulation in the brain to receive information and impart depth..

Pick up the links in the wiki article, CornSweet illusion to understand more of this..

from this article from Harvard -
http://adsabs.harvard.edu/abs/2012SPIE.8291E..17D

"Cornsweet profiles to produce a local contrast that leads to a perceived brightness increase.

"Similarly, Cornsweet profiles in disparity can lead to an illusion of depth.

"Applying them skilfully at depth discontinuities allows for a reduction of the overall disparity range to ensure a comfortable yet convincing stereo experience.

"The present work extends the previous idea by showing that Cornsweet profiles can also be used to enhance the 3D impression. "

A little bit technical but, when the left and right images have a shift in them slightly, based on subtle light dark changes (the light dark changes in the L R images enhance the effect), the eyes and brain put together the "message".

Here's a few more examples. We will do this in very simple B/W shapes to show how the "shift" is part of the method used in the image to create what the brain believes is "perspective" depths..

Make 4 boxes/circles with that slight refocusing closer, the box in the center right is FORWARD above the circles.. The box in the center LEFT is behind the circles. (take a few moments to let the eyes and brain adjust..relax then see the perspective appear..)

This illustration lacks the Cornsweet "optical 3D enhancement sweetening", so it takes a few more moments for the brain to assemble the image into something that makes "sense". Cornsweet process improves the speed of information reconstruction.

Hypnotically watching a movie for instance, letting it "just sink in" is the technique that was noticed how it could be applied to convey messages "over-time" in animated pictures (moving pictures, video's).

And here, this is a mindbender, an impossible object in 3D using the same technique of shift.. (without CornSweet enhancement)

In this one below, just make 3 images, then look at the center "virtual image" for the 3D effect..

Old subliminal inlays, or blip-verts, rapidly flashed in messages for fractions of a second were the early attempts to reach the subconscious, and were outdone by using this newer method of putting information at the periphery, using the brain merge technique to re-assemble.. (This method allows for layering of even many more images per "frame" with depth of focus changes - we may get into that in another thread.)

This method allows for continual programming, can be applied to any social media.. the more one watches the more one would be given the section of programming, like a forced education that one would simply never consciously know one had been "given" the message, the belief system (no matter how outlandish it may be).. it's amazing how the brain works. :)

There is TV technology that presents 3D without glasses or impossible to see blury images.

They have not been "produced" because you need two things to make it work - a "hood" basically to block right and left sides out of view, and your eyes need to cross slightly to get the effect. Both these things make the TVs likely not very practical and hard on your eyes.

You only really need to divide the viewing plane into a "right" and "left" image - each a complete image from each the right and left camera. The 'hood" or side blockers, blinders is I guess the best term, in combo with the slight crossing of the eyes will give you a full colour 3D effect, but the effect is limited mostly to depth and very little protrusion, so proximity to the screen is also a prohibitive factor.

This video here can be used to actualize the effect:

kpCup7k3uZ0

What you need to do is put the video full screen, and move your face to about 1.5 feet from your monitor. Press play and cross your eyes a little until you see three (three will be formed from the two existing ones) equal sized "views". Then slowly bring your hands around from the sides about 1-2 inches from your face and begin blocking out the right and left "views" until you see only the center view, then slowly focus your eyes until you can bring the center view into focus without relaxing your eyes too much that they get "uncrossed". Viola! 3D! If you can't seem to get it right, try playing with the distances a little, some people may not have the eye control to be able to get this effect so don't cry if you can't make it work ;)

Yup, showing that videos can be done in the 3D perspective technique is good.

What I had been pointing out, is this method with image layering, and putting the left and right images at the corners of the main video image (or the top or bottom like a ticker scroll in a news broadcast, that position in other words), if one is either focusing closely, or even focusing far, looking off into the distance type of focus with respect to one's monitor, the image is there virtually as the third image formed in the middle..

That third image is the subliminal that is directly driven into the brain..

This image shows the HOW behind how it's done.. If you do a close "cross eye" near focus, to create 4 images you get the right center image's square floating above the circle.. If instead, you do a far field focus, look at something far past the computer screen that same right center image's square is floating behind the circle..

All of this shows how the brain can re-assemble what it believes is something that makes sense to it. All of that dub-in fills in the gaps where the brain tries its best to bring sensation, a full story..

An interesting, perhaps loose, testament to the broader fact that despite our best attempts to be logical and "scientific", our own perceptions, down to the senses themselves can be augmented by the brain to make things fit into the belief structure we have, or the expectations that form our persistent "reality".

Reminds of the legend that when the White man arrived to the Americas, many locals could not see their huge massive ships anchored off the shore, this perception did not fit into what the knew as "reality", therefore was tossed out, to make what makes the most amount of "sense" based on those beliefs, fit.

It appears our brain does this a fair bit, at all different levels of our perception, often based on beliefs, or what we expect.

Believe nothing, consider everything ;)

so true so true...

I recall an episode of Star Trek where folks were given these holographic game glasses, to play a game which required the user to LET go and let it happen, let the game run, get the stimulation, and in the process continually, PLAYing the game, going with the sensation of how "good it was" to simply let go, go with it.. they were implanted by an enemy ship who knew how the mind worked, and what good feeling stimulation would provide one... And they almost won, the "enemy aliens"..

ref: http://en.wikipedia.org/wiki/The_Game_(Star_Trek:_The_Next_Generation) "the GAME",
and the script here:
http://en.memory-alpha.org/wiki/The_Game_(episode)

here is some fun to try with the 3 circles..

When doing the FAR FIELD, relax the eyes and look past the screen, when you create the two additional images center screen for 4... look carefully at the red and the blue dots, in the virtual 3D image... when one fully lets go, the red dot merges with the white dot, and it sorta goes invisible, and to do that one has to "let go".. another illustration of the brain reward mechanism to have a desired sensation (3D over a normal 2D flat effect)... the 3D gives the brain the extra reward pleasure, and of course that is what the enemy ship wanted.. to get in with pleasure rewards..

TidBit
4 Lights or 5 Picard was asked by his captor.. he said I SEE 4.. After a while he eventually said to Riker, u know, I thought at the end I did start to see 5... :) which is what his captor was saying all you need to agree is with the lie, and we will be happy..
