I was testing / learning your interface in the tomato branch and one of<br>
the data requested to setup the camera tracking is the size of the<br>
camera sensor.<br>
As I had been using a cell phone, Samsung it took me a while to find out<br>
about the camera and the sensor then once that was resolved I needed to<br>
know about the specs of the sensor.<br>
So I end up with that site that you maybe interested in and also for the<br>
others users<br>
<br>

<br>
I have some past experience of tracking data on 2D images having<br>
produced stitching engines in the 90s for mocap, TV and also space apps<br>
like satellites and the hubble.<br>
<br>
With the app PT Gui de Helmut Derch at the university of Iena, I<br>
developped some interfaces using trackers defined for hot spots by<br>
users. We had lots of problems with that technique from the user<br>
parts, screen resolution, human vision, and also quality of the<br>
pictures / images resolution and so on..<br>
So at the end we did a magnifier, like the one you have, but that did<br>
not much for the selection of hot spots.<br>
Since then using Fourier transforms for automatic discovery of hot spots<br>
has been really a working path..<br>
I am looking forward to see your progress in that field because lots of<br>
things can be done from there..<br>
Take care<br>
Yves<br>
