Improve text detection accuracy on the numerical digits. Including the period (.) symbol detection is a good addition but not required. False and missed detections often happen on most number digits. For example, 0 becomes 6, 9 becomes 3, and so on.

Steps to Reproduce

  1. Replace the Region5 entry on /extract.py at line # 19 with other regions defined in /data/coordinates.json:
    • img = getRegion(img, 'Region3') (set to Region3)
  2. Take note of the mismatching digits on the extracted text.
    • original (cropped, downscaled) image:
      test
    • extracted text:
      extracted
