One formal language to describe them is the ISL (Image Schema Language), a logic language combined by different formal calculi and first-order logic that builds on creating hierarchical families of logical micro-theories that is able to represent different degrees of specification of the image schemas.
A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional ...

The visual system also has several non-image forming visual functions, independent of visual perception, including the pupillary light reflex and circadian photoentrainment. This article describes the human visual system, which is representative of mammalian vision, and to a lesser extent the vertebrate visual system.
As image–producers, they are related to perceptions. "While the concept belongs to the understanding and its instance to perception, the schema has, so to speak, a foot in either domain. As rules for the production of images the schemata … are linked to the understanding; as rules for the production of images they are linked to perception."
"Schema" comes from the Greek word schēmat or schēma, meaning "figure". [7]Prior to its use in psychology, the term "schema" had primarily seen use in philosophy.For instance, "schemata" (especially "transcendental schemata") are crucial to the architectonic system devised by Immanuel Kant in his Critique of Pure Reason.
A visual language is a system of communication using visual elements. Speech as a means of communication cannot strictly be separated from the whole of human communicative activity which includes the visual [1] and the term 'language' in relation to vision is an extension of its use to describe the perception, comprehension and production of visible signs.
A human visual system model (HVS model) is used by image processing, video processing and computer vision experts to deal with biological and psychological processes that are not yet fully understood.
