How to train by tesseract 4.00

[yang3...@gmail.com]

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!

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.

Hi Shree,

I've been trying to use this repo but I keep getting this error when I run any target with OCR-D.

 make training

combine_tessdata -u /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.traineddata  /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.

Failed to read /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata

Makefile:97: recipe for target 'data/unicharset' failed

make: *** [data/unicharset] Error 1

thank you!

You have some problems with your path configuration, check the error message:

Failed to read /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata

the path does not make sense. And also the command line:

combine_tessdata -u /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.traineddata  /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.

you probably also have a "blank" after "/usr/share/tessdata".

Bye

Lorenzo

But still i don't know why this happens I haven't modified anything in the Makefile!! What would I need to change?

[Lorenzo Bolzani]

The TESSDATA_PREFIX maybe?
