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.
