Measuring uncertainty in human visual segmentation
Fig 9
Uncertainty modulates the perceptual mapping between features and segments.
Left: tested images (same images and data as Fig 7). Right: differential variance (or weight vector, see main text) best relating oriented wavelet features to human responses. Top: low uncertainty case (texture orientation distributions are weakly overlapping). Bottom: high uncertainty case (texture orientation distributions are strongly overlapping). Maps are reconstructed without regularization (λ = 0).
