Codes, heterogeneities, and structures: Visual information and visual art

Codes are mechanisms in which signs are actualized. They relate various sign sides to each other. These sign sides can be represented as heterogeneities (diversity, relations, differences), some are organized with the help of various differences – identities formulated in a specific way. The basis of the codes of visual perception and art are primarily the heterogeneities of the elements perceived directly (contours of objects, sizes, directions of movement, light and color irritants, etc.). A structure, conceived of as a manner of connection, is a principle for constructing a kind of a whole and is the center of an organized heterogeneity.
