“…This idea was corroborated by Csatho et al [73], who suggested that the salience of symmetry is a linear function of the noise proportion. Recently, this view was refined by van der Helm, who argued that symmetry detection deviates from Weber-Fechner law [74]. The magnitude of the deviation depends on regularity-to-noise ratio.…”

The human visual system is highly proficient in extracting bilateral symmetry from visual input. This paper reviews empirical and theoretical work on human symmetry perception with a focus on recent issues such as its neural underpinnings. Symmetry detection is shown to be a versatile, ongoing visual process that interacts with other visual processes. Evidence seems to converge towards the idea that symmetry detection is subserved by a preprocessing stage involving spatial filters followed by information integration across the visual field in higher-tier cortical areas.

“…Therefore, any holographic regularity can be divided into substructures, all of which have the same regularity as each other. Unlike the earlier transformational model, the holographic model provides an account of the residual structure in symmetry + noise patterns and of the perceptual structure of Glass patterns . The model explains why detection of reflectional symmetry is not affected by number of elements, while repetition is more difficult to detect with more elements .…”

Symmetry is an important and prominent feature of the visual world. It has been studied as a basis for image segmentation and perceptual organization, but it also plays a role in higher level processes, such as face and object perception. Over the past decade, there has been progress in the study of the neural mechanisms of symmetry perception in humans and other animals. There is extended activity in the ventral stream, including the lateral occipital complex (LOC) and VO1; this activity starts in V3 and it occurs independently of the task (automatic response). Additionally, when the task requires processing of symmetry, the activation may emerge for objects that are symmetrical, even though they do not project a symmetrical image. There is also some evidence of hemispheric lateralization, especially for the LOC. We review the studies on the cortical basis of visual symmetry processing and its links to encoding of other aspects of the visual world, such as faces and objects.

“…This research showed that symmetry is one of the visual regularities, that is, one of the regularities the visual systems of humans and many other species are sensitive to [23][24][25]. For instance, even if a pattern is far from perfectly symmetrical, humans are well able to detect the presence of symmetry [23,26]. Not surprising therefore, symmetry detection is believed to be an integral part of the perceptual process that is applied to every input.…”

“…For instance, qualitatively, the formal notion of holographic regularity seems to supply a perceptually relevant border between visual and nonvisual regularities [54], and also the holographic difference in structure between symmetry (point structure) and repetition (block structure) seems perceptually relevant [55]. Furthermore, the quantitative model W = E/N accounts for various perceptual differences between symmetry and repetition, including the fact that symmetry is better detectable than repetition, and it accounts for the detectability of symmetry in the presence of noise (for more details, see [21,26,49,51,56,57]). …”

The Influence of Perception on the Distribution of Multiple Symmetries in Nature and Art

Much is already known about single mirror symmetry, but multiple mirror symmetry is still understood poorly. In particular, perceptually, multiple symmetry does not seem to behave as suggested by the number of symmetry axes alone. Here, theoretical ideas on single symmetry perception and their extensions to multiple symmetry are discussed alongside empirical findings on multiple symmetry perception. The evidence suggests that, apart from the number of axes, also their relative orientation is perceptually relevant. This, in turn, suggests that perception is responsible for the preponderance of 3-fold and 5-fold symmetries in flowers as well as for their absence in decorative art.
