Data association by loopy belief propagation

WebAug 29, 2010 · To further improve both the GLMB and LMB filters' efficiency, loopy belief propagation (LBP) has been used to resolve the data association problem with a lower computational complexity [16,17]. Web2.1 Loopy Belief Propagation Loopy Belief Propagation (LBP) [20, 26] is an inference algorithm which approximately calculates the marginal distribution of unob-served variables in a probabilistic graphical model. We focus on LBP in a pairwise Markov Random Field (MRF) among other prob-abilistic graphical models to simplify the explanation. A ...
