Yes - that'll also make the algorithm run faster.

So overall, it must be possible, right?

I'm sure it's possible.  What I'm not sure about is whether the kind
of naive algorithm that I could come up with after just a few minutes
thought would be effective.  It might take some rather serious image
processing algorithms to get a measure of how well focussed the image
is - and that might be a major learning experience!

Good Luck!  Tell us what works.

I have no idea how to access the camera from a programming language, nor do I have any experience in raw vision proccessing. Do you know how to do any of these previously meantioned? Timothy (...) (22 years ago, 18-Dec-02, to lugnet.robotics)
