Bias-variance plots for each blur scenario with optimal selection of (λ,β). These plots illustrate the relative performance of each reconstruction noise model. In the detector blur dominated scenario, the three models perform comparably. In both the equal blur and source dominated blur scenarios, the correlated noise model shows the best performance and the white noise model shows the worst performance. The relative gain of the correlated noise model is greatest in the source blur dominated scenario.
