One thing I found is when I cropped my test image to include only one
horizontal word, tesseract handled that fine. So... if I could detect
the grid pattern in which all the letters are laid out, maybe I could
feed the letters to an OCR tool one word or char at a time and get the
results I'm looking for. That would also give me clear info about
spatial relations between the letters, so I could group them correctly
into words.
So maybe I should first be asking about detecting the grid established
by the scrabble letters.
(It's actually Bananagrams letters. My nerdy grandkids like to use
Scrabble letters when playing Bananagrams so they can see who gets high
score.)
Thanks -

Thanks for the followup on this. I experimented some with tesseract
and came to the same conclusion.
Since the values assigned to each character are standard wthin
Scrabble, I don't really need to detect those tiny numerals. But the
alpha chars are of course essential.
I believe there must be a way to get there. Thankfully no one is
pressuring me to finish it, so I can explore.

After a second read I think it will be hard to find a service to do that
for you. And this is not doable using tesseract or similar from
LiveCode:
AFAIK, no "ordinary" OCR software is able to detect and read horizontal
*and* vertical text and distinguish clearly between the board's "Score
text" and the "Scrabble letters". You (or your service) would have to
write an own "learning routine" for that.
E.g. the algorithm described here:
http://rasdasd.com/projects/Scrabble_Detector/Scrabble_Paper.pdf
There are also approaches for own specialized boards like here
https://github.com/eladj/ScrabbleOCR
You could try to use the java from there via LC Builder's FFI.

I want to [programmatically] take a picture of a Scrabble board and

take from that image the characters displayed in it, and maintain the
organization of the text. In other words, I want to convert the text
displayed in the image to text strings.
Any ideas where I should start?
I would love to be able to do it in my app. However I'm not completely
against uploading the image to a service that would do it for me; I am
only mostly against it.
