Update: on a batch of 60 meters, I was able to get 46 meters recognized. First i ran a batch that runs tesseract on every .tif, and names the output <picture name>.txt. Then, I simply wrote a batch script to compare a text file of known meter numbers against every tesseract output file using findstr. The results show up as <picture name>.tif:<picture name>.txt.
Is there any way to optimize the pictures to make the text easier to read before processing? I tried converting to grayscale last night, but it actually hurt the results. The meters that don't come across all seem to have minimal glare problems. At any rate, in the trials, I have already saved myself a ton of time, and for that I am happy. Where's the donate button?
