Figure 4From: Pedestrian tracking with an infrared sensor using road network informationFictive example to illustrate the proposed association method. Particle mixtures of two targets are shown. The means of the particle mixtures are indicated by a plus-symbol and a circle-symbol, respectively. Two detections are illustrated by stars. A Gaussian density assumption would result in the switched version of the association decisions given by the particle based approach presented in this work.Back to article page
