Ask HN: Google Vision vs. AWS Textract vs. Tesseract?
I've been playing around with Tesseract to extract text from pdf files and have found it a little disappointing, even after doing some pre-processing to the image (300dpi, binarization, de-skewing).
Does anyone have good experiences with OCR tech for extracting text from PDFs? Especially scenarios where you can't control / improve the initial image.
