Figure 4.

Expanded view of ℓ₂ reconstruction errors from one-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. In all but one case, jittered subrandom sampling performs nearly identically to jittered pseudorandom sampling.
