Confidance evaluation of the tracking #714

Closed Ciro1990 closed 1 year ago

Ciro1990 commented 1 year ago

Dear all,

I would like to ask if trackpy computes any metrics that describes the confidence/uncertainty of a specific assignment

Ideally, I would like to know if, in any frame, the assigned track ID has crossed a certain threshold, in order to raise a flag for me to correct that assignment manually.

Thanks! Ciro

Hi Ciro,

I don't believe that there is any way to get this output, do you mean like what is the confidence that the located object is actually an object?

I believe that the returned ep column is what you're looking for, it can be used as an estimation of uncertainty, where a larger number is a lower confidence! Source: http://soft-matter.github.io/trackpy/dev/tutorial/uncertainty.html
