How can I track the position of a hand fingers in a video?

Hello, I am working on a project about Parkinson disease, and I would like to know how to indentify and track the position of a hand fingers in a video. I tried using image segmentation to recognise the hand in the image and it worked but I don't know how to select an exact point on the finger and then track its exact position along the video. As you can see on the following images, the aim is to select a point in each finger and then track its position.

 I also attach the video I want the fingers to be tracked, for anyone who wants to try to solve it.
Any help is very welcome. Thank you. Lecus.

Hello,

The idea in your case is to detect motion if present, bertween consecutive video frames. Please follow the links below which could be useful.
