I need to get every symbol alone to pass them to neural network and recognize them!

that's a lot of "want", while you need "skill"

apologies, did not want to put you down there ..

next steps:

  • findContours
  • get boundingRect of each
  • crop content
  • resize to something fixed (the input size of your network)
  • feed that into ml
