Natural scene statistics predict how humans pool information across space in surface tilt estimation
Fig 8
Human prediction error from the global model with fixed circular pooling.
Mean prediction error is plotted as a function of the diameter of the pooling region. Mean prediction errors are computed across all tilts and human observers. The black dashed line indicates the mean prediction error for the local model. The gray dashed line indicates the prediction error for a “local” model that computes the image cues from an area matched to that implicitly used by the best global model (see Discussion). Data from Exp 1 and Exp 2 are shown in the left and right columns, respectively.
