Superlevel sets Γ0.25(I) for two pruning levels on the noisy toy dataset: l = 14, a too low cut-off and l = 39, an adequate value. Blue pixels are regions where both sets are overlapping while red ones show regions highlighted by the l = 14 version but not by the l = 39 one and are mostly found in the background noise of the pattern.
