Abstract


I-MuPPET Framework

Most tracking data encompasses humans, the availability of annotated tracking data for animals is limited, especially for multiple objects. To overcome this obstacle, we present I-MuPPET, a system to estimate and track 2D keypoints of multiple pigeons at interactive speed. We train a Keypoint R-CNN on single pigeons in a fully supervised manner and infer keypoints and bounding boxes of multiple pigeons with that neural network. We use a state of the art tracker to track the individual pigeons in video sequences. I-MuPPET is tested quantitatively on single pigeon motion capture data, and we achieve comparable accuracy to state of the art 2D animal pose estimation methods in terms of Root Mean Square Error (RMSE). Additionally, we test I-MuPPET to estimate and track poses of multiple pigeons in video sequences with up to four pigeons and obtain stable and accurate results with up to 17 fps. To establish a baseline for future research, we perform a detailed quantitative tracking evaluation, which yields encouraging results.

Additional Results


Pose Estimation and Tracking of Multiple Pigeons

I-MuPPET is trained on our labeled single pigeon data set. Nevertheless we are able to estiamte and track poses for multiple pigeons.


Single pigeon. In this video I-MuPPET estimates and tracks the pose of one pigeon. This single pigeon is not from our labeled single pigeon data set that we used for training.



Multiple pigeons. In the following videos I-MuPPET estimates and tracks the pose of multiple pigeons, although only trained on data containing one single pigeon.

Failure case: From 'ID 1' we see that in some cases of the multi-pigeon video sequences, pose estimation is not accurate. Please keep in mind that I-MuPPET is trained on our labeled single pigeon data set only.

I-MuPPET is trained on the odor trail tracking data set from DeepLabCut.
