Multi-Target Tracking

We start with general comments on the multi-target tracking (MTT) problem and some mathematical preliminaries. Multiple-hypothesis tracking (MHT) is a leading paradigm for MTT. We describe the target and sensor mathematical modeling assumptions that enable track-oriented MHT. Next, we derive the MHT recursion and illustrate its use with illustrative examples. We provide broader context by describing connections between MHT and the overall taxonomy of MTT methodologies. We discuss recent advances in cutting-edge MHT processing and their relevance to operational surveillance applications.
Despite the proven success of MHT as a methodology for MTT, computational constraints and other fundamental performance limitations may lead to unacceptable performance in some settings. We discuss the benefits that can be achieved with multi-stage MHT processing. In many settings, judicious distributed MHT processing enables improved performance over (necessarily suboptimal) centralized MHT. We provide illustrative examples from several domains. Additionally, we describe recent advances in graph-based tracking, a fast (approximate) approach to MHT that provides improved results in certain applications.
