I am trying to fine-tune Tesseract for dot-matrix fonts such as that in the picture below. When the dots are closely spaced together and touch, Tesseract can more or less handle the dot-matrix font with some fine-tuning and image processing. However, when the dots do not touch, as in the picture below, Tesseract struggles.
I read in An Overview of the Tesseract OCR Engine <https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/33418.pdf> that the first step in Tesseract's processing pipeline is a connected component analysis (second paragraph of Section 2). Since the letters in a dot-matrix font do not form connected components, I am wondering if Tesseract's connected component analysis may be one reason that Tesseract struggles on the image below. Is there a command to see how Tesseract performs connected component analysis on this image?
