currently I'm working on an overlay for a piano with the Epson BT-200, so I decided to try to recognize the piano via the keyboard / keys. But because the white and black keys are big areas of the same color and it is a repetetive pattern the sdk has its problem with recognizing it.
That is the image I've worked with so far:
Maybe someone of you can give me a tip on how to recognize the keyboard better.
What is not suitable for me is:
- Trying to recognize the piano with another part then the keyboard, because my App has to work with different pianos and as they are built very differently i can't use another feature of my special piano.
- To large markers or similar, because they have to stay on the piano while it is played. So they mustn't disturb the piano player.
