Specular Image Structure Modulates the Perception of Three-Dimensional Shape

摘要: Summary Retinal images are produced by interactions between a surface’s 3D shape, material properties, and surrounding light field. In order to recover the geometry of surface, visual system must somehow separate aspects image structure generated shape from its properties or lightfield in which it is embedded. Attributing wrong physical source would cause interpret changes one property (such as reflectance) another shape). Many previous studies have shown that does not conflate specular reflectance with [1–6], but they did assess conditions where be computationally most difficult disentangle these different sources structure. Here, we show varying roughness curvature surfaces embedded natural lightfields can strongly modulate perceived shape. Despite complexity interactions, how an image’s gradient mediates interpretation reflection change Our findings provide coherent explanation when why reflections impact reveal static surface simplified fields, experimental methods used may explain their inconsistent results.
