VSS 2018 – Shape scission: causal segmentation of shape
Warts, cracks, causal shape segmentation. Research on shape perception usually focuses on the estimation of local surface geometry through cues like stereopsis, shading, or texture. Here, we argue that observers use these shape estimates to infer other object… Read More
Fechner’s Aesthetics Revisited
Isn’t it beautiful? Gustav Fechner is widely respected as a founding father of experimental psychology and psychophysics but fewer know of his interests and work in empirical aesthetics. In the later 1800s, toward the end of his career,… Read More
Perceptual representation of visible surfaces
What is a surface, anyway? Two experiments are reported in which we examined the ability of observers to identify landmarks on surfaces from different vantage points. In Experiment 1, observers were asked to mark the local maxima and… Read More
Statistical Shape of 3D Objects.
Statistical distribution of shape on a 3D object. A bell pepper from Norman et al. Each color represents a class of shape ala Koenderink’s “Shape Index”. The histogram below shows the distribution along with a key to the… Read More
