Thanks for this. i know about the usage of the tesseract. i have multiple images where i can't improve image quality so i want to improve my model to get text from it. are you saying that text detection will not improve by training? Because i don't have an issue with text recognition most of time it right. can you tell me how can i improve the model to get more text from the image? I am using psm 11 where it find lot's of text but some are missing.
