Figure 5.
Expanded view of ℓ2 reconstruction errors from two-dimensional rejection-based sampling methods. Errors from pseudorandom, jittered pseudorandom, subrandom, and jittered subrandom schedules are indicated by circles, crosses, solid lines, and dashed lines, respectively. The deleterious effects of highly coherent non-jittered sampling are manifest at 10% and 5% sampling densities as high ℓ2 errors. Jittered subrandom sampling is practically indistinguishable in performance from jittered pseudorandom sampling in all cases.
