Effects of masking LSBs on LTB segmentation. (a) Performance for N = 9 observers in Experiment 4a, segmenting LTB stimuli using a proportion of unbalanced micro-patterns (${\pi }_U$), set at 75% JND for each observer, as measured in Experiment 1a. We see similar performance for most observers in the absence of a masker (neutral case, neu) as well as with a masker having congruent (con) and incongruent (inc) orientation. Here the congruent case pools across in-phase and opposite-phase conditions. (b) Performance for same observers for congruent stimuli which are in-phase (con-0) and opposite-phase (con-180).
