any chance to get this .tiff converted to text?

[boris]

Hi Commnunity,

I started using Tesseract today because I need it for a small project. I have run tesseract with the attached .tiff file but I get very poor results. Am I doing something wrong or is the quality/contrast of the .tiff just too bad?

The example file was taken from a .bmp screenshot and then converted without compression to .tiff

I would be very greatful for any answers. Please consider that I am novice to Tesseract when answering.

Best Regards,

   Boris

I was going to suggest the tips from https://code.google.com/p/tesseract-ocr/wiki/ImproveQuality

but, just OCRing the image without any changes in VietOCR (GUI frontend for tesseract) with German traineddata gives perfect result - see image.

What version are you using, on what platform, ??

I would suggest that you try Vietocr - download the german traineddata and give a try ..

Hi Shree,

many thanks for your help. I have installed the german trained data and VietOCR but I still get very poor results.

"Bme a\|fpn|fen mn" is what I get

I must be doing something wrong. 

My platform is Windows 8.1 

Best Regards,

   Boris

Please choose german in the dropdown for language on right hand side.

Hi Shree,

I have changed language to German but it won´t realy improve.

Anyhow, I am thinking of programming my own OCR for my project as I need 100% accuracy. It won´t be a big deal because the font is always the same.

Regards,

   Boris

Do look at https://code.google.com/p/tesseract-ocr/wiki/ImproveQuality 

for pre-processing steps for your images to improve recognition regardless of the OCR you use.

Hi Boris,

Be sure to select Screenshot Mode. The image has too low resolution.

Hi Quan,

thanks for your help.

Sorry, this might be a silly question, but as told I am novice with Tesseract ;-)

How do I select the Screenshot mode?

Regards,

  Boris

[ShreeDevi Kumar]

In VietOCR's image menu, check 'screenshot mode'

Use the filters submenu to experiment with other settings to improve your image.

Look under properties for the dpi, convert your input images to 300dpi as they are currently low res (72dpi or so).

experiment :-)

The command syntax are:

java -jar vietocr.jar -?

vietocr -?

The command-line mode does not support rescaling of images though. Use ImageMagick's convert command to rescale or resize.
