hi list
i would like to ask more advanced programmers for a good starting point.
I would like to do a minimalistic OCR for 7 segment numbers in PD. The
picture would be captured by a simple webcam.
What is a good way to realize that ??
I found some perl-scripts that seem to do that, or some OCS software
that one could send the images to.
What do you think, how complicated would it be to write an external
that does that ?
Help is very much appreciated
bye luigi
Ok this is referring to my last post.
I guess i could use pix_fiducialtrack to to the simple OCR-Task.
I would just need to adjust the "all.trees" file, right ??
Is there any more information on how to do that ? How the "region
adjacency graph" is built ??
Thanks Luigi

yep, there is a paper by kaltenbrunner et al. referenced in the help-patch. (actually i thought it was referenced; but it seems like it is not; it should be available on the reacTable homepage though)
however, fiducials (as used by reacTVision) do very simple hierarchical analysis of the the images (which white blob is contained in which black blob and vice-versa), i don't think that your 7segment targets will match the criterion of being hierarchically unique.
