You can test with the finetuned traineddata file from https://github.com/Shreeshrii/tessdata_shreetest/blob/master/engmorse.traineddata
Download the file (raw file) Use it with `-l engmorse` If you have not not placed it in your tessdata directory identified by TESSDATA_PREFIX also provide the path with `--tessdata-dir /path/to/finetuned/traineddata` ubuntu@tesseract-ocr:~/TEST$ tesseract morse.jpg - -l eng Warning: Invalid resolution 0 dpi.
