Hello

Is there anyway where Tesseract 4 can be trained for checkbox ? I want to train Tesseract for empty checkbox , checkbox with cross/check sign. Default English trained data does not identify checkbox.I tried defining new font using jTessBoxEditor and trained it using this tool. but no success.

You will have a better chance of a successful response if you can provide some additional information about your situation. At a minimum, please provide:

- your exact version of jTessBoxEditor, tesseract (ie 4.0.1 rather than 4) & all of the pre-requisites listed on the jtessboxeditor website (http://vietocr.sourceforge.net/usage.html) eg javascript

- some minimal information about your environment ... linux/windows? python/.NET?

- the exact error message that you receive in jTessBoxEditor and exact steps to reproduce it

Assuming this is occurring immediately post-install for you, providing step-by-step of how you installed jTessBoxEditor would likely also help.

Cheers,

Josh

jTessBoxEditor is for training for Tesseract 3.0x format only. For 4.0x, please consult https://github.com/tesseract-ocr/tessdoc/blob/master/TrainingTesseract-4.00.md

Im not sure that v4 incompatibility claim is accurate. The landing page of the website for jtessboxeditor only lists compatibility with v2 & v3. The changelog for the application itself specifies that the latest update offers support for tesseract 4.1.1 (which is why I requested clarification on version numbering ... using an earlier version with tesseract 4 would not work)

correction: my bad guys, previous poster is correct. the changelog on the site is a mishmash of changes for 3-4 different applications.

latest available jtessbox version supports no later than tesseract 3.05-dev. for what its worth, I havent made up my own mind on the best option for zone selection. my own preference is something that wont lock me into v3, though.
