Low Z separation

Thomas Rebotier Oct 8, 2010:

and regarding the fine, it is obvious that you won't pay any fine, given that the traffic camera won't react in time to catch your image, and that the cop car won't catch you either. Keep driving near the speed of light!

Thomas Rebotier Oct 8, 2010:

I think I agree with meirs that Z is the depth (profondeur), but in the context of signal detection it may also be the Z-score, which is the number of standard deviations between the two signals. Since the context is not crystal-clear, you should ask the client.

Redshift Just reminds you of the physics question - if you speed on the road so much that you see a red traffic light as green, what overspeeding fine you pay ?

kashew Oct 7, 2010:

Unless we are intergalactic and it's on about redshift (usually small z).

Tony M Oct 7, 2010:

I think Meirs is right Z is the depth dimension, the 'extra' one that makes these systems special.

Presumably, different sampling intervals or display techniques can be used to give differing degrees of prominence to the depth dimension of the image, depending on specific requirements.

X ray detection??? or infrared detection (IR) ?

meirs Oct 6, 2010:

Z is the depth dimension Where X and Y are resp. width and height (usual 2D dimensions). I would leave as Z - or use something like profonditee (no sure about FR spelling)
