Ambiguous images or reversible figures are visual forms that create ambiguity by exploiting graphical similarities and other properties of visual system interpretation between two or more distinct image forms. These are famous for inducing the phenomenon of multistable perception.
Digital photography spans a wide range of applications with a long history. Much of the technology originated in the space industry, where it pertains to highly customized, embedded systems combined with sophisticated remote telemetry. Any electronic image sensor can be digitized; this was achieved in 1951.
Digital imaging. Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, [1] such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images.
1902 – Arthur Korn devises practical telephotography technology (reduction of photographic images to signals that can be transmitted by wire to other locations). Wire-Photos are in wide use in Europe by 1910, and transmitted to other continents by 1922. 1907 – The Autochrome plate is introduced.
Hyperrealism is a genre of painting and sculpture resembling a high-resolution photograph. Hyperrealism is considered an advancement of photorealism by the methods used to create the resulting paintings or sculptures. The term is primarily applied to an independent art movement and art style in the United States and Europe that has developed ...
In photography (particularly digital photography), purple fringing (sometimes called PF) is the term for an unfocused purple or magenta "ghost" image on a photograph.This optical aberration is generally most visible as a coloring and lightening of dark edges adjacent to bright areas of broad-spectrum illumination, such as daylight or various types of gas-discharge lamps.
Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape. [ 1] Image geometry correction compensates for the distortion created by off-axis projector or screen placement or non-flat screen surface ...
In photography, acutance describes a subjective perception of sharpness that is related to the edge contrast of an image. [1][2] Acutance is related to the amplitude of the derivative of brightness with respect to space. Due to the nature of the human visual system, an image with higher acutance appears sharper even though an increase in ...
