A visual routine is a means of extracting information from a visual scene.. Shimon Ullman, in his studies on human visual cognition, proposed that the human visual system's task of perceiving shape properties and spatial relations is split into two successive stages: an early "bottom-up" state during which base representations are generated from the visual input, and a later "top-down" stage ...
