 Hello, 
 I am basically working in electronics field and new to C#.Currently 
 I am working on one project (Image processing in C#) where i am using 
 C#,where in one of the part i have to detect text or digits of 7 
 segment 
 display image for that on google i found Tesseract  solution.

 For experiment i have first try to convert normal text image in to 
 text file and it is working fine for some of the basic images but it 
 is not 
 working with 7 segment display.so i came to know i required trained 
 data 
 file for 7 segment.

 For training 7 segment data i follow the steps which are shown in 
 vidoe of below link:https://www.youtube.com/watch?v=i_1-hGsXxy8.
 But the output.txt file showing in that video is not generating in 
 my case.Due to which after using trained 7 segment data file ,i am 
 getting 
 garbage value in text file.So for checking that i am getting proper 
 trained 
 file or not , i have follow the procedure which is shown on that video 
 but 
 it is giving an error  like outpt.txt file not found.Is this happened 
 because of missing otput.txt file or something else i am missing to 
 do.I 
 have follow all the steps which are shown in that video for training 7 
 segment data.

 Also i have installed jTessBoxEditorFX.jar, serak trainer & 
 Tesseract-ocr v3.02.So at the end i am just stuck in the point 
 where i don't know where i am going wrong,is my procedure is wrong or 
 software installation is not proper because after installing tesseract 
 there is red cross mark against tesseract.

 Please somebody help me to figure it out.If possible please provide 
 me 7 segment trained data file and also the exact steps to trained 7

Hey Dominik, Is ssd.traineddata working for you?
Are you getting decimal point?

Re: [tesseract-ocr] Re: seven segment display - 4.0 traineddata

[Shree Devi Kumar]

I had deleted the files but can rerun the training again.

It will be helpful if you can provide a sample text of the kind of display
you are trying to recognize - eg. is it just digits,  or also includes
letters - which ones, only uppercase??? Please provide at least 100 lines
of text.

A sample image as well as any info on similar looking fonts will be helpful.

[tesseract-ocr] Re: seven segment display - 4.0 traineddata

[Dominik Helleberg]

Hi, the download gives a 404 error :( 
Since I'm trying to detect 7 segment displays with tesseract 4, i would 
really like to try it out.
Do you have the download still at hand somewhere?
Thanks!
