Tesseract on .Net > End Line Character

[Ruwanthaka Ranasinghe]

Hi All,

I’m training new Language Pack for Sinhala Language @ Sri Lanka.

 It works as expected but at every line end word/ Character join with the next new line start word without any spaces added.

 Can anyone help me on this?

Ahanks in advance

can you send me an example of your training images, just one or two...it is the most critical part on your technique.

 

you probably need more distance between each character in the x axis in your trainer files.

please fins the attachment of images which i use as training sample.

I don't think you can train tess with these kind of images, to
Sinhala. I have failed training with these kind of images

any way currently it's working as expected way , and result almost over 90%.

only major issue i faced that end line issue which i pointed earlier.

[Lahiru Himash Madusanka]

It will work with this image. But when using other images that we
didn't used for the training, It will give some conjunction errors. I
couldn't able to overcome this line error

[Ruwanthaka Ranasinghe]

this is interesting , i used above 13 such files (all are same as above)  as training samples ,

now it 's working fine with above 90% of accuracy.

[Ruwanthaka Ranasinghe]

can you send me the sample image with it's BOX file ?

[Lahiru Himash Madusanka]

I'm in trouble @Ruwanthaka, While trying to upload these files. All
got deleted by accident. :( Failed recovery attempt due to low space
in my HDD. I'm totally lost. Only I got my image files.

[Lahiru Himash Madusanka]

trying to re-train all my images :(

It looks like some people have trained Tesseract for Sinhala; see
http://www.ucsc.cmb.ac.lk/sdu/research.html &
http://192.248.22.122/ocrsinhala/

However as far as I can see they aren't sharing their .traineddata
file, or the source files for it. It would be a good idea to contact
them and ask if they can share those with you, and with the
community more broadly, so we can potentially improve things in the
future.

If they don't respond, instructions on training Tesseract are on the
wiki:
