Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
The Rubin vase illusion, where it is ambiguous which part is the figure and which the ground Shapes which can be read as a word once the viewer recognises them as being the isolated negative spaces of a word. Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision.
The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. [1] It is a simple wire-frame, two dimensional drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side.
Figure and ground (media), a concept developed by media theorist Marshall McLuhan; Figure–ground (perception), referring to humans' ability to separate foreground from background in visual images. Figure-ground perception is one of the main issues in gestalt psychology. Figure-ground in map design, the ability to easily discriminate the main ...
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.
As the time difference between the target and the mask increases, the masking effect decreases. This is because the integration time of a target stimulus has an upper limit 200 ms, based on physiological experiments [3] [4] [5] and as the separation approaches this limit, the mask is able to produce less of an effect on the target, as the target has had more time to form a full neural ...
The use of negative space is a key element of artistic composition. The Japanese word "ma" is sometimes used for this concept, for example in garden design. [2] [3] [4] In a composition, the positive space has the more visual weight while the surrounding space - that is less visually important is seen as the negative space.
