This paper addresses the problem of multiple extended objects (EOs) tracking, which has attracted increasing attention recently due to the developments of high-resolution sensors. Specifically, the state of an EO is modeled by the Gamma-Gaussian-inverse-Wishart (GGIW) distribution, and the message passing inference method, which provides a high efficient implementation for multi-target tracking, is adopted to propagate the posterior of the distributions of multiple EOs. The performance of proposed method is verified via simulation experiments.
