"Adding" new fonts to Tesseract eng.traineddata
ocr, python, tesseract
Solution
Should use a different name, e.g., `eng1.traineddata`. That way you can use the new data with the original one by specifying the language option `-l eng+eng1`.
Problem
As far as I know, Tesseract 3.x comes with 6 English (correct me if I'm wrong) fonts. I need to train Tesseract for more 5 types of fonts. I need only capital letters and digits (no special characters or symbols). I followed various processes for example: Adding New Fonts to Tesseract 3 OCR Engine and also used tools to automate the process like Serak Tesseract Trainer for Tesseract 3.02 For generating box files I used QT Box Editor After using above tools I get `eng.traineddata` file. All tutorials tell me to add this `eng.traineddata` file to the `Tesseract-OCR\tessdata` folder, but doing so, it will replace the original `eng.traineddata` file. After doing this will I lose the default fonts that come with Tesseract 3.x ? How can I Add new fonts? Its still not clear to me. I hope someone can help me here. Thanks.
