OCR Text Recognition of White text on Black Background

Hello,

I trying to capture text in a DOS like environment that only supports White text on Black background. I have tried recognizing the same text with black text on white background in notepad with success. How can I configure OCR to read the white text?

  • Hi Jose,



    To improve the recognition level up to the acceptable level, it is recommended to avoid factors that can lower it - edges smoothing, font smoothing, the multi-color background, etc. For more information, refer to the Using Optical Character Recognition - Overview help topic. If you experience problems with character recognition of black text on the white background, please post a screenshot of the window area where you need to recognize text (in the BMP or PNG format because they are lossless). We could try to adjust the recognition settings to help you achieve a better recognition accuracy.



    Also, a better solution could be to use the Text Recognition functionality of TestComplete. Have you tried using it? If you have not, read about it in the Using Text Recognition Technology - Overview help topic.



    Does it work for you?

    Let me paint a better picture. I am remotely logging into a client system via a KVM (java app) and capturing the screen during POST to see if the system reports the correct string to an update. (i.e. a firmware update to an option ROM). I capture the screen but no text is recognized. I have the font file for the text being displayed on the screen during POST for better OCR recognition but still no luck. I have attached a cropped png of the screen of an example of the text I am trying to recognized.
