Difference trained data for Chinese

[Yang Yu]

Good day!

Recently I was using tesseract (4.0 alpha) to do Chinese OCR and it works really great. Now I want to pick up a best model to use but I find several versions. What is the difference between them?

1. chi_sim from https://github.com/tesseract-ocr/tesseract/wiki/Data-Files (around 50M)

2. chi_sim from https://github.com/tesseract-ocr/tessdata/tree/master/best (around 13M)

3. chi_sim_vert from https://github.com/tesseract-ocr/tessdata/tree/master/best (around 13M)

4. HanS from https://github.com/tesseract-ocr/tessdata/tree/master/best (around 16M)

All of them can work but the results are slightly different. From my own evaluation #4 is the best, but I don't have any insight.

Appreciate for any help.

Thanks! That is pretty clear.
