It is expected to be clearer for people who are not familiar to models to make comparisons and evaluations of grazing eﬀects. To test the feasibility of the model, ... (Herbivore) Optimization Hypothesis (McNaughton, 1979). It indicates that WitrynaFig. 7 (a) shows the average OSPA (2) of all compared algorithms increase with the Poisson mean number of the clutter. The reason is that the increase of clutters leads to more false alarm tracks. Furthermore, it also shows the overall accuracy of the compared algorithms increases in the order of MHT, MHT-DBSCAN, GTMHT-1best, and …
