From: The Southampton-York Natural Scenes (SYNS) dataset: Statistics of surface attitude
(a) Egocentric surface attitude for natural, built and indoor scenes. Each larger plot gives log(probability density) over slant and tilt, collapsed across elevation. Smaller plots give log(probability density), conditioned on a particular range of elevations. (b) Distribution of egocentric surface tilt, collapsed across slant, for the three categories, the radial axis gives log probability. (c) Distribution of egocentric slant, collapsed across tilt. (d) Distribution of slant (collapsed across tilt) in world coordinates, i.e. relative to gravity. Zero slant corresponds to horizontal surfaces viewed from above, 180° corresponds to horizontal surfaces viewed from below.
