How to apply Kalman Filter to the unfiltered results by DeepLabCut?

Currently, DeepLabCut supports more basic filters such as SARIMA or median filter for postprocessing the estimated pose results. Is there a third party or integrated way to posprocess the estimated pose results using Kalman Filter without really reinventing the wheel?

Searching for ‘kalman’ in DLC GitHub repository brings me to this issue https://github.com/DeepLabCut/DeepLabCut/pull/736 however I don’t see an integration already or a manual.

Currently, the results are in a CSV and include the X and Y for each keypoint at each step at a time.

Hi, I’m also interested in a Kalman filter implementation working in deeplabcut. I’m trying to have an implementation merging the images of two cameras.
