How to improve OCR recognition accuracy

**Question**
I want to use EasyOCR, but the results are not very satisfactory, and I'm looking for a solution.

First of all, my test images are mainly in Japanese and English. I added DOCLING_SERVE_ARTIFACTS_PATH="", but the recognition quality is still not very good. However, the results are very good in the demo at https://www.jaided.ai/easyocr/. I'd like to know how to solve this issue.

Of course, if I can recognize the test images better, I don't necessarily have to use EasyOCR.

I would be extremely honored to receive your help.

Start by reviewing the provided test image, parsed image, and EasyOCR demo comparison, along with the DOCLING_SERVE_ARTIFACTS_PATH setting. Reproduce the reported Japanese and English recognition results and determine whether the issue is configuration, model selection, or an OCR integration problem; done means a confirmed cause and a specific, reproducible improvement.
