===== Descriptors =====

Given the aspects of the visual field ([[figure-ground|figure/ground]], [[motion|motion]], [[gradient|gradient]]), **descriptors** are structures that describe the interrelationship of the figures within the visual field. 

A given descriptor can refer to figure/ground, motion, or a gradient, though obviously the application will differ. It is possible to use size to create a figure/ground relationship, such as a grid of squares with one much smaller square. It is possible to use size to create motion, such as a square getting larger then smaller over time. And it is possible to use size to create a gradient, such as a row of ten squares, each one getting slightly smaller. 

The most common descriptors are [[size|size]], [[proportion|proportion]], [[shape|shape]], [[position|position]], [[direction|direction]], [[orientation|orientation]], [[texture|texture]], [[speed|speed]], and [[stasis|stasis]].
