Add complex preprocessing to get better OCR results from tesseract. Possible ways of doing this include:

Cropping the image around the text
Straightening pages
Rotating the image if the text is incorrectly oriented https://arccoder.medium.com/straighten-an-image-of-a-page-using-opencv-313182404b06

The image now gets reorientated so the text is horizontal.
