Statistics of three-dimensional natural scene structures

Dynamic Analysis of Three Dimensional Asymmetric Isolated Structures

Subjective randomness and natural scene statistics.

Accounts of subjective randomness suggest that people consider a stimulus random when they cannot detect any regularities characterizing the structure of that stimulus. We explored the possibility that the regularities people detect are shaped by the statistics of their natural environment. We did this by testing the hypothesis that people's perception of randomness in two-dimensional binary ar...

Natural scene statistics mediate the perception of image complexity

Humans are sensitive to complexity and regularity in patterns [YKM13, FK97]. The subjective perception of pattern complexity is correlated to algorithmic (Kolmogorov-Chaitin) complexity as defined in computer science [LV08], but also to the frequency of naturally occurring patterns [HGS10]. However, the possible mediational role of natural frequencies in the perception of algorithmic complexity...

Natural scene statistics at the centre of gaze.

Early stages of visual processing may exploit the characteristic structure of natural visual stimuli. This structure may differ from the intrinsic structure of natural scenes, because sampling of the environment is an active process. For example, humans move their eyes several times a second when looking at a scene. The portions of a scene that fall on the fovea are sampled at high spatial reso...
