Comparison of Two Approaches for Detection and Estimation of Radioactive Sources

Figure 4

Trace plot (a) of the number of radiological point sources 𝑟 in the first 500 samples drawn from 𝑝(Θ∣𝑧^𝑏,𝐳,𝐼) during the probabilistic exploration phase using RJMCMC (after the completion of the annealing phase) and the corresponding posterior distribution (b) for the number of sources, 𝑝(𝑟)≡𝑝(𝑟∣𝑧^𝑏,𝐳,𝐼).
