ocrengine - recognise dot-matrix font #6

Train the OCR to recognise dot matrix font, for example dot matrix font example

howff commented 1 year ago

Partially 'solved' by downsampling (resizing) the image before OCR. Implemented via this commit https://github.com/SMI/dicompixelanon/commit/446f8dd0a87b6ec7bbb78724e193372a3fdc030d

Testing involved different reductions (by 2 or 3), and different methods such as nearest neighbour, bicubic, etc. INTER_NEAREST was best on the test data, but may have been a fluke, so chose NEAREST_AREA.
