Evaluating Crowd Density Estimators Via Their Uncertainty Bounds

Jennifer Vandoni, Emanuel Aldea, Sylvie Le Hégarat-Mascle

Abstract: In this work, we use the Belief Function Theory which extends the probabilistic framework in order to provide uncertainty bounds to different categories of crowd density estimators. Our method allows us to compare the multi-scale performance of the estimators, and also to characterize their reliability for crowd monitoring applications requiring varying degrees of prudence.
