Unmaintained. Alternative traineddata avaliable at https://github.com/Shreeshrii/tessdata_ssd or alternative implementation that don't use tesseract: https://github.com/arturaugusto/7seg-ocr.
OpenCV-Python + python-tesseract real-time image preprocess and OCR.
Trained data for 7 segments font avaliable under letsgodigital folder.
Web-app using trained data: http://ocr.sytes.net (Not always up, due to the low cost server)
Reference: https://code.google.com/p/python-tesseract/
Tips to achieve better results:
- Use erode to avoid gaps between the segments.
- Avoid direct light on the display (I use parchment paper to diffuse the light)
