Hello users!

I would like to know if ARToolKit can give a "confidence value"  (a value
between 0 and 1)when a marker is detected.
If the answer is YES, how can I obtain this value?
The idea is to select the best marker detected when the camera is detecting
more than one marker.

Thanks in advance
Best regards

PD. Is it available any new tutorial of ARToolkit?. I have  the tutorial of
the v.2.33

That's right. You might want to look at the simpleVRML demo app that comes 
with ARToolkit 2.52. This app uses the confidence value in a similar way 
to how you want to use it.

The answer is yes, if you look at the structure ARMarkerInfo you will 
see there is entry called 'cf', this is your confidence factor. I use 
it, as you say, for choosing the best marker from many.
