Evaluation Metrics

In AnimalTrack, we employ commonly used CLEAR metrics (MOTA, MT, ML, FP, FN, IDs and FM), ID metrics (IDP, IDR and IDF1), and HOTA metrics (HOTA, AssA, and DetA) for evaluation.


Evaluated Trackers

We extensively evaluate 14 state-of-the-art MOT algorithms on the proposed AnimalTrack. Table 1 shows these trackers.

Below are overall evaluation results and comparison.

Figure 3. Visualization and comparison of object appearance features for re-identification between pedestrians and animals using t-SNE. The same target object is represented as dots with the same color. We choose the first 30 target objects in the first 200 frames for visualization. We can clearly see that the appearance features of animals are more difficult to distinguish compared to pedestrian appearance features, resulting in new challenge for animal tracking.
