    The barber pole illusion is a visual illusion that reveals biases in the processing of visual motion in the human brain. Benham's top: When a disk that has lines or colours on it is spun, it can form arcs of colour. Beta movement: Movement that appears to occur when fixed pictures turn on and off. Bezold Effect

  3. Optical illusion - Wikipedia

    en.wikipedia.org/wiki/Optical_illusion

    The hypothesis claims that visual illusions occur because the neural circuitry in our visual system evolves, by neural learning, to a system that makes very efficient interpretations of usual 3D scenes based in the emergence of simplified models in our brain that speed up the interpretation process but give rise to optical illusions in unusual ...

    en.wikipedia.org/wiki/List_of_paradoxes

    Optical illusion: A visual illusion which suggests inconsistency, such as an impossible cube or the vertical-horizontal illusion, where the two lines are exactly the same length but appear to be of different lengths.

    en.wikipedia.org/wiki/Geometrical-optical_illusions

    Ponzo illusion in a purely schematic form and, below, with perspective clues. However, almost all geometrical optical illusions have components that are at present not amenable to physiological explanations. [4] The subject, therefore, is a fertile field for propositions based in the disciplines of perception and cognition. [5]

  6. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    Not every person can see the 3D illusion in autostereograms. Because autostereograms are constructed based on stereo vision, persons with a variety of visual impairments, even those affecting only one eye, are unable to see the three-dimensional images. People with amblyopia (also known as lazy eye) are unable to see the three-dimensional images.

    The cost database may be stored in relational database management system, which may be in either an open or proprietary format, serving the data to the cost estimating software. The cost database may be hosted in the cloud. Estimators use a cost database to store data in structured way which is easy to manage and retrieve. [2]

  9. Chubb illusion - Wikipedia

    en.wikipedia.org/wiki/Chubb_illusion

    The Chubb illusion is similar to another visual illusion, the contrast effect.The contrast effect is an illusion in which the perceived brightness or luminance of an identical central visual target form on a larger uniform background varies to the test subject depending on the ratio of the central form's luminance to that of its background.
