If I close one eye, I can't see animals in a cage very well. If I
have 2 eyes open, my brain gets the 2 perspectives and
"cancels" the cage so I can see what's happening inside.
I like taking photos. Sometimes there are cages, other times
power lines. But my camera has only one eye, and those
artefacts are obscuring the view.
Some new phones have 2 cameras next to each other. Can the
video feed from these be combined to cancel out cages,
power lines, or other artefacts?

Technically, the wire is not an "artefact" as that term is normally
used in the context of digital image processing (that is, image
processing is not the particular ars by which it's factum). |
|
| |
Of course, you might have meant that the wire itself (not its
image) is artificial, whereas the poor zoo animal is a natural child
of nature. If you can make *that* distinction with a pair of
cameras, then your invention has exciting applications in the field
of organic food certification. |

It should be possible to do this, if the two lenses are far enough apart, and if the distance from camera to fence is much less than from camera to subject. |
|
| |
One potential problem, though. If the animals behind the fence catch onto this idea, they might learn how to wink alternate left and right eyes, eliminating the wire fence and allowing them to escape. |
|
| |
Or, if they cottoned onto the idea, they could learn how to bail. |
|
| |
//But what about the horizontal wires ?// |
|
| |
Turn the camera 90 degrees so one lens is above the other, shoot, then rotate the image back 90 degrees the other way. Or, you could build a camera that includes a third lens, offset in the vertical direction from one of the other two, and use an algorithm to decide which pixels to use from which view to blot out various unwanted objects. |

Hello, [BigBrother]; haven't seen you here for a while. :-) |
|
| |
Oh, and welcome, [peterburk]. |
|
| |
A light field camera could probably do this ... |
|
| |
It's his third idea ... should we start roasting the newbie yet ? |
|
| |
People have been doing this for ages? |
|
| |
But it's hard to tell an innovation, because that is about how a random person who can do something easily by accident. That is where the money is at. |
|
| |
This technique is still going to be a composite, a mind see, not a factual representation. I wonder, if the difference between the processed two camera shots and the photons capture instance of one camera without the fence, is going to be significant. |
|
| |
At least with the Lytro (linky) it is trying to capture more information about the one instance. |
