September.  At that time the only goal was to get it working like it did
originally.  Then it was also kind of fun to look at the other OpenCV
examples, see how they worked and convert Move/Flow/Gabor.  Now it was
thought was a good time to upgrade the version of OpenCV so test material
was needed and that is when Style and Puzzle were added.

We did not get any real feedback that it was useful to have some OpenCV
plugins available to Cinelerra/CGG so left it at that - although I did put
a note out on the OpenCV forum suggesting that maybe someone there would be
interested last September.

If there is more emphasis on using FindObject, it might be a good idea to
improve the user interface as you can see from the demo what a difficult
time I had getting the box surrounded!   GG/Phyllis
