Visual Regularity
To obtain simplest codes, SIT applies coding rules that capture the kinds of regularity called iteration, symmetry, and alternation. These have been shown to be the only regularities that satisfy the formal accessibility criteria of
- (a) being so-called holographic regularities that
- (b) allow for so-called hierarchically transparent codes.
A crucial difference with respect to the traditional, so-called transformational, formalization of visual regularity is that, holographically, mirror symmetry is composed of many relationships between symmetry pairs rather than one relationship between symmetry halfs. Whereas the transformational characterization may be better suited for object recognition, the holographic characterization seems more consistent with the build up of mental representations in object perception.
The perceptual relevance of the criteria of holography and transparency has been verified in the so-called holographic approach to visual regularity. This approach provides an empirically successful model of the detectability of single and combined visual regularities, whether or not perturbed by noise.

Famous quotes containing the words visual and/or regularity:
“The chess pieces are the block alphabet which shapes thoughts; and these thoughts, although making a visual design on the chess-board, express their beauty abstractly, like a poem.... I have come to the personal conclusion that while all artists are not chess players, all chess players are artists.”
—Marcel Duchamp (1887–1968)
“The question of whether it’s God’s green earth is not at center stage, except in the sense that if so, one is reminded with some regularity that He may be dying.”
—Edward Hoagland (b. 1932)
