Hi Leo,

Your example has such good contrast that you might consider using the colors to 
identify single characters. I have attached a quick sample of what I mean. I 
used opencv and defer greatly to the blog post I reference at the top of the 
script, but the idea would be to try to catch single characters using opencv’s 
“inrange” function. I would use tesseract on the image first and weed out blobs 
for further processing based on the coordinates of what tesseract has already 
detected. I would then use single character mode on what’s left. Feel free to 
ping me if you are interested in this approach.
