'''Structural information theory''' ('''SIT''') is a theory about [[perception|human perception]] and in particular about visual perceptual organization, which is a neuro-cognitive process. It has been applied to a wide range of research topics,<ref>Leeuwenberg, E. L. J. & van der Helm, P. A. (2013). ''Structural information theory: The simplicity of visual form''. Cambridge, UK: Cambridge University Press.</ref> mostly in visual form perception but also in, for instance, visual ergonomics, [[data visualization]], and [[music perception]].

SIT began as a quantitative model of visual [[pattern classification]]. Nowadays, it includes quantitative models of [[symmetry|symmetry perception]] and [[amodal perception|amodal completion]], and is theoretically sustained by a perceptually adequate formalization of visual regularity, a quantitative account of viewpoint dependencies, and a powerful form of neurocomputation.<ref>van der Helm, P. A. (2014). ''Simplicity in vision: A multidisciplinary account of perceptual organization''. Cambridge, UK: Cambridge University Press.</ref> SIT has been argued to be the best defined and most successful extension of [[Gestalt psychology|Gestalt ideas]].<ref>Palmer, S. E. (1999).  ''Vision science: Photons to phenomenology.'' Cambridge, MA: MIT Press.</ref> It is the only Gestalt approach providing a [[calculus|formal calculus]] that generates plausible [[percept|perceptual interpretations]].
