Is it possible to introduce the "Shake the box" algorithm into trackpy? #634

Open lanlankai opened 3 years ago

lanlankai commented 3 years ago

We do the experiment on copepods to see the possible collective motion. The trackpy suite is nice to identify them, but we have a large portion miss-match during the tracking when we increase the number density of copepods. it seems that the so-called shake the box algorithm can resolve this problem. It is a pity that I don't know how to do the program. Is it possible to introduce this algorithm to the trackpy?

@lanlankai I think we would be happy to take a PR from you or your students to implement this, but no one is available to do the work for you.

If you have collective motion https://soft-matter.github.io/trackpy/v0.4.2/tutorial/prediction.html#Prediction:-Beyond-Simple-Random-Walks might be able to help you already?
