Recognizing keys of piano on the image

I am newbie in image processing, so sorry if it will seem dumb to you.

I am building app that will show user the keys that he/she must press. I want to recognize the keys on piano.

How can I achieve this? What can you advise me(tutorials, online courses)?

Instead of recognizing all keys, try something simpler that wiil just do.

For instance recognizing the piano as a whole would be enough I presume. Just ask the user to press C key then each time one octave upper C or whatever. It would be easy to divide 7, the distance between the two keys, even on 2D image of 3D perspective.

Try openCV tutorials, it is free and well documented. Just read all and think how can you use this feature for your task. Spend 1-2 month, and ask here again but more distinctly, like: I use binarization and morphology operations and Hough line detectors but now I have this problem...

You may use terms "binarization", "morphology operations" and "Hough line detector" as a hint.
