identifying text chars in an image

[Phil Davis]

Thanks for your great ideas Hermann. In my next experiment I think I'll 
start by looking for any scrabble tile by looking for its [known] 
background color, and then work out to its edges. That should give me 
both the grid cell size and a starting point for discovering all cells 
in the grid.

Unless anyone knows of something simpler?

Thanks -
Phil
