Re: [tesseract-ocr] How to train by tesseract 4.00

[ShreeDevi Kumar]

If you want to train using fonts, use tesstrain.sh. See the wiki pages
regarding training.

If you want to use scanned images, then see
https://github.com/OCR-D/ocrd-train for using line images and their ground
truth transcriptions to create box files, lstmf files and training.

[tesseract-ocr] Unicharset_extractor meet ICU ERROR

[yang3781590]

Environment
   
   - Tesseract Version: <4.00>
   - Platform: 

Current Behavior:

C:\Users\Jerry\Desktop\新建文件夹>unicharset_extractor chi_my.font.exp0.box
Extracting unicharset from box file chi_my.font.exp0.box
ICU ERROR: U_FILE_ACCESS_ERROR


But I find this will be solved by use [tesseract-ocr-setup-4.00.00dev.exe] 
. It will occur by use [tesseract-ocr-w64-setup-v4.0.0-beta.1.20180414.exe]

[tesseract-ocr] How to train by tesseract 4.00

[yang3781590]

I have read that on the version of 4.00, the box file can be used  only 
need to cover a textline instead of individual characters.

So I make a box file like this 

若存在，试求出实数λ的值； 0 0 256 48 0

Then I want to ask how to train it.

Or is it the same version 3?   【tesseract chi_my.font.exp0.tif 
chi_my.font.exp0 nobatch box.train】

or there is other better method.

Thanks!
