If you're interested, I will make it available to you (incl source code), so you can include it with your FACAR distribution.
@Tylo,

Sounds great! I had been playing with AutoCrop 1.1 calls to detect and use the values directly (like GripFit does), but I found that sometimes AutoCrop just doesn't get it right. Human intervention to say "this is it" is still needed or you may find out later that you lost a lot of time.

If you have time, you might try to modify AutoCrop algo to do something like this: instead of using a predefined threshold, scan the lines and compute the maximum M for all of them. Then stop when (M(n)-M(n-1)) > E, where E is the possible error of a black area (determined experimentally). I think this way human intervention can be left aside.

I'd do it myself, but C++ is quite obscure to me. I'm an old timer.

Please e-mail me your code (I PMed you my e-mail address).
