Discrimination of length (top) and orientation (bottom) for a line at various orientations around the clock. Nevertheless, there is an oblique effect for target configurations that do not directly address these "oriented" neural elements early in the visual path into the brain. [11]
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.
Orientation columns are organized regions of neurons that are excited by visual line stimuli of varying angles. These columns are located in the primary visual cortex (V1) and span multiple cortical layers. The geometry of the orientation columns are arranged in slabs that are perpendicular to the surface of the primary visual cortex. [1] [2]
The central visual element, known as element of design, formal element, or element of art, constitute the vocabulary with which the visual artist compose. These elements in the overall design usually relate to each other and to the whole art work. The elements of design are: Line — the visual path that enables the eye to move within the piece
A representation of hierarchical feature extraction and combination in the visual system. Visual hierarchy, according to Gestalt psychology, is a pattern in the visual field wherein some elements tend to "stand out," or attract attention, more strongly than other elements, suggesting a hierarchy of importance.

The element of value is compatible with the term luminosity, and can be "measured in various units designating electromagnetic radiation". [6] The difference in values is often called contrast , and references the lightest (white) and darkest (black) tones of a work of art, with an infinite number of grey variants in between. [ 6 ]
The human visual system will settle on either of the interpretations of the Rubin vase and alternate between them, a phenomenon known as multistable perception. Functional brain imaging shows that, when people see the Rubin image as a face, there is activity in the temporal lobe, specifically in the face-selective region.
Form perception is the recognition of visual elements of objects, specifically those to do with shapes, patterns and previously identified important characteristics. An object is perceived by the retina as a two-dimensional image, [1] but the image can vary for the same object in terms of the context with which it is viewed, the apparent size of the object, the angle from which it is viewed ...
