Where can I find a dataset with hands?

Question

Neural networks

I want to create a model that will determine in real time whether the index finger is extended or not.

For example, the finger is extended.

And here the finger is not extended.
I need a dataset where there will be similar marked-up pictures.
If there is one, then great. If not, where do they come from? Are there any research centers? How can you get such a dataset? Only to create?

Do you have no hands, make your own dataset?
