Hello Lorenzo, We're fine tuning en.traineddata without modifications with charset restriction within [A-Z0-9]. We're using the default parameters and the model converges very fast. We have #1376 images from Google image used to test the accuracy. The reported accuracy is min(detector, recognizer). These #1376 images can't be directly used with tesseract and requires a detector and preprocessor.
