1. 1. Tracking of Pedestrians Using Multi-Target Tracking Methods with a Group Representation

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Jakob Jerrelind; [2020]
   Nyckelord :Multiple target tracking; random finite sets; probability hypothesis density; PHD; cardinalized; CPHD;

   Sammanfattning : Multi-target tracking (MTT) methods estimate the trajectory of targets from noisy measurement; therefore, they can be used to handle the pedestrian-vehicle interaction for a moving vehicle. MTT has an important part in assisting the Automated Driving System and the Advanced Driving Assistance System to avoid pedestrian-vehicle collisions. LÄS MER

3. 2. Birth Density Modeling in Multi-target Tracking Using the Gaussian Mixture PHD Filter

   Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Författare :Rongrong Chen; Min Zhu; [2008]
   Nyckelord :tracking; Gaussian Mixture PHD filter; birth density;

   Sammanfattning : A recently established method for multi-target tracking which both estimates the time-varying number of targets and their states from a sequence of observation sets in the presence of data association uncertainty, detection uncertainty, noise and false alarms is the probability hypothesis density (PHD) recursion. The approach involves modeling the respective collections of targets and measurements as random finite sets and to propagate the posterior intensity, which is a first order statistic of the random finite set of targets, in time.
