Distinguishing shadows from surface boundaries using local achromatic cues.
PLoS Computational Biology, 2022 In order to accurately parse the visual scene into distinct surfaces, it is essential to determine whether a local luminance edge is caused by a boundary between two surfaces or a shadow cast across a single surface.
