Training Tesseract OCR for a specific document about tesstrain HOT 4 OPEN

Could you please elaborate on what you are trying to achieve by training a specific document (type)? What do you expect to change compared to using the existing models?

Thank you for your response @stefan6419846 .

I ran Tesseract default English model on this image and the output is very bad. So, I want to train Tesseract specifically for this document to improve the output but I don't know how I can generate the training dataset(line images, *.gt.txt & box files) from these images. If you could suggest me some tools to create the dataset from these images, that would be wonderful.

I have not tried it, but I would argue that better preprocessing on your side (feeding Tesseract with specific ROIs with appropriate preprocessing per ROI instead of the whole page, ...) might be easier and sufficient.
