The LED Reader: Continued...
Here are the steps required for the machine vision software that "finds" the LED digits in the digital images of the clocks:
  1. Convert the digital image to greyscale
  2. Find the Horizontal (H) and Vertical (V) Edges
  3. Convert the H and V edges to Strokes
  4. Remove any Strokes that are too short or too long
  5. Group the Strokes into Digit Candidates
  6. Identify the Digit Candidates as Digits
  7. Group the Digits into Digit Groups
What does this look like in pictures?
