Natural scene statistics predict how humans pool information across space in surface tilt estimation

Spatial statistics of tilt in natural scenes.
A Stereo images and stereo distance maps of real-world scenes. The distance data is co-registered to the image data at each pixel. B Groundtruth tilt corresponding to the image in A. Groundtruth tilt at each pixel is computed directly from the data in the distance maps. C Prior distribution of groundtruth tilt, computed from 600 million groundtruth tilt samples in the natural scene database. D Mean absolute tilt difference from the center target tilt as a function of spatial location. The color represents the tilt difference across all pixels in all images in the natural scene database. E Mean absolute tilt difference conditioned on the groundtruth tilt at the target location.
