Contrast-negation and texture synthesis differentially disrupt natural texture appearance

摘要

Contrast-negation and texture synthesis each disrupt the appearance of natural textures. Both manipulations preserve some features (e.g. isophotes in contrast-negation, summary-statistics comprising the synthesis model) while disrupting others (e.g., local phase in contrast-negation, higher-order statistics in texture synthesis). Here, we examined the extent to which contrast-negation and texture synthesis each introduce or remove critical perceptual features for discrimination from natural textures using a 4AFC oddball detection task.
