## Context We want to implement more functionalities for evaluating pose estimation model performance and for detecting outliers - i.e. erroneous/implausible pose predictions. [LightningPose](https://github.com/danbider/lightning-pose) currently uses a set of 3...

Provide coordinates for both `time` and `frame`

**Is your feature request related to a problem? Please describe.** Currently in our `xarray.Dataset` we only have one `time` axis, the units of which may vary depending on whether the...

[xarray wraps Pint-xarray](https://xarray.dev/blog/introducing-pint-xarray) allowing the assignment of physical units. Relevant example from the above article: ```python ds = xr.Dataset({'a': 2, 'b': 10}) ds.pint.quantify({'a': 'kg', 'b': pint.Unit('moles')}) ```

Smooth trajectories using a median filter

2

DeepLabCut has some support for smoothing/filtering pose tracks, in the form of the `filterpredictions()` function in the [`filtering.py` module](https://github.com/DeepLabCut/DeepLabCut/blob/main/deeplabcut/post_processing/filtering.py). They offer three options: - Median filtering. This is the most...

Rethink definition of displacement vector

2

Right now the displacement vector at t is defined as the vector from t-1 to t. For the first frame, it is defined as the zero vector. Although this naturally...

Currently our data structure assumes that all individuals (animals) are tracked with the same keypoints (body parts). This assumption holds for most, **but not all** pose estimation datasets. We should...
