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 ...
The encoding of surfaces is thought to be an indispensable part of visual perception, forming a critical intermediate stage of visual processing between the initial analysis of visual features and the ability to recognize complex stimuli like faces and scenes. [7] Amodal perception; Autostereogram; Filling-in; Gestalt psychology: 'closure'
Closure, the appearance of a figure to be completely contained within the visual field, and thus entirely surrounded by ground. [7] A figure with closure stands out because it looks like "a thing." The proclivity for closed objects is so strong in human visual processing that humans will perceive closure even when figures are only mostly closed.
Law of closure. Gestalt psychologists believed that humans tend to perceive objects as complete rather than focusing on the gaps that the object might contain. [38] For example, a circle has good Gestalt in terms of completeness. However, we will also perceive an incomplete circle as a complete circle. [39]
The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
Closure: the principle of closure refers to the mind's tendency to see complete figures or forms even if a picture is incomplete, partially hidden by other objects, or if part of the information needed to make a complete picture in our minds is missing. For example, if part of a shape's border is missing people still tend to see the shape as ...
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.
A version of Rubin's vase. The Rubin vase (sometimes known as Rubin's vase, the Rubin face or the figure–ground vase) is a famous example of ambiguous or bi-stable (i.e., reversing) two-dimensional forms developed around 1915 by the Danish psychologist Edgar Rubin.
