Natural scene statistics predict how humans pool information across space in surface tilt estimation
Fig 5
Local and global models for tilt estimation.
A The local model obtains a local tilt estimate given three local image cues. B The fixed circular pooling model uses a circular pooling region with the same size for all target groundtruth tilts (cf. Fig 2D). C The adaptive elliptical pooling model uses an adaptive pooling region with a different size, aspect ratio, and orientation for each groundtruth tilt (cf. Fig 2E). As the average area of the adaptive elliptical pooling region changes, the relative area, orientation, and aspect ratio of the pooling regions are held fixed.
