摘要: This paper first validates that the track-oriented multiple-hypothesis tracking recursion holds in case of state-dependent detection probabilities, as is generally assumed. Next, we seek to extend allow for unresolved measurements. The formulation requires some simplifying assumptions, including an assumption targets be resolved at birth and a restriction on size target clusters. approximation admit (factored) form, leads nonlinear optimization problem. We discuss multi-stage architecture provides simpler more robust processing approach practical settings.
