Hi Djibril, I am afraid that this is an old topic and he may not work with invoices anymore. I am also interested in extracting information from invoices. Have you tried to use tesseract with a dictionary to improve accuracy? Because invoices have some particular data fields. You can see the manual here: https://github.com/tesseract-ocr/tesseract/blob/master/doc/tesseract.1.asc#config-files-and-augmenting-with-user-data Tell me if you have better result. I will also tell you if I have. Best,
