ABSTRACT
Human visual perception is an active process of the brain starting with primal processing in the visual system. Visual perception (or vision) can be defined as the process or the result of processes of building an internal representation of an object or a scene in the mind of the viewer. This encompasses entities or relations that are believed to exist in an external reality and that can be derived by processing reflected light rays (or an absence thereof). In other words, visual perception is the human ability to interpret a scene by processing information that is contained in visible light by the eye-brain mechanism.
