You might have realized the different videos and photos popping up all over the internet of Snapchat filters seeming to pick up on on unseen faces. But what is this ? A simple software malfunction or are the intricate Snapchat algorithms actually able to recognize faces of the dead.
The Snapchat filters are able to transmogrify your face into a hamster, harry potter, a piece of toast, etc …..
But for this gimmicky feature that does make up Snapchat there is an insane amount of technology behind it.
For the functions they have to be able to recognize distinct features in a face, then the program has to model the structure of your face in 3d space, taking into account the rotation and occlusion of the overlaid prop effects
So to find the face in the given space, Snapchat uses the Viola Jones Algorithm. This works by scanning the image data repeatedly, calculating the different shades of grey ( grey-scale pixel value ).
By doing this the app picks up on the light hitting the fact, even when the light cant be seen by the human eye. So normally the light would hit the bridge of your nose and your forehead first.
But does that mean it can mistake a lumpy bit of sofa for a human face ?
See how he tells it where to go and the faces manifest …….
It is possible, it all depends on how the light is hitting the object. Like you see guys doing a Face swap with a plug socket etc.
But we do see this same technology put to use in some of the more expensive ghost hunting equipment. The SLS Camera ( The Structured Light 3d Scanner ).
One of the designers state ” The Machines software can make mistakes, however when functioning in the dark. So without light tampering and when a figure appears then it should stay there even when the camera is moving.”
See how he also is able to request the spirit to do certain things, making the chances of this happening accidental minute.
The only way to prove this is catching spirits is to give a command, tell it to appear again and facing pointing the camera in a different part of the room. Then you know that is a floating pooch face appears again then the chances of it being another glitch in that moment are almost 1000000/1.
As technology advances in such crazy ways everyday we are guaranteed to find some accidental extra functions of devices or software. Lets just hope there are more like this that can allow us to see more ghosties.
