However, these methods fail to take distribution information of pixel noise into tracking consideration, which then results the degradation of detection performance. In this paper, we address this problem by modifying the measurement model of IP-PMHT to allow for incorporating statistical information of pixel noise. A key point to achieve this is that Interpolated Poisson follows a thinning property, which means that the energy from clutter can be modeled with a parameterized Interpolated Poisson in the IP-PMHT. We replace the parameterized Interpolated Poisson with a given distribution, which describes the pixel noise, and propose a new tracking method. An important feature of this new method is that it retains the advantages of the H-PMHT, meanwhile naturally incorporates the prior information about pixel noise in target tracking. Through the Monte Carlo simulations, we prove the superiority of this new method in dim target tracking. |
