In visual surroundings

the mapping from hierarchical and multiscalar relationships into visual perception is showed as the visual propensities in analyzing and organizing the surroundings. The simplest relationships are local position and orientation relationships

and their corresponding visual propensities are the visual position and orientation orders. At phenomenological level

position and orientation orders are explicitly expressed in an energy model. Several K kinds of perceptual binding emerge as global solutions of this energy model. A general theory for perceptual organization including visual position and orientation orders

can be used to consider the other clues for perceptual organization

such as closeness

similarity

symmetry and so on. This theory provides a general approach to visual representation and learning.
