  2. Perspective control - Wikipedia

    en.wikipedia.org/wiki/Perspective_control

    Perspective control. Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective. The control would: make all lines that are vertical in reality vertical in the image. This includes columns, vertical edges of walls and lampposts. This is a commonly ...

  3. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]

  4. Distortion (optics) - Wikipedia

    en.wikipedia.org/wiki/Distortion_(optics)

    Distortion (optics) Not to be confused with spherical aberration, a loss of image sharpness that can result from spherical lens surfaces. In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration .

  5. Optical proximity correction - Wikipedia

    en.wikipedia.org/wiki/Optical_proximity_correction

    Optical proximity correction ( OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement integrity of the original design, after ...

  6. Esotropia - Wikipedia

    en.wikipedia.org/wiki/Esotropia

    Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called ...

    Later this year, JPMorgan will expand the use of a generative AI tool known as "Moneyball" to help portfolio managers avoid bad calls, such as potentially selling hot stocks too soon, ...

  8. Flat-field correction - Wikipedia

    en.wikipedia.org/wiki/Flat-field_correction

    This variation is called vignetting, and can be corrected by selectively brightening the perimeter of the image. Flat-field correction ( FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital ...

  9. Prentice position - Wikipedia

    en.wikipedia.org/wiki/Prentice_position

    The Prentice position is an orientation of a prism, used in optics, optometry and ophthalmology. In this position, named after the optician Charles F. Prentice, the prism is oriented such that light enters it at an angle of 90° to the first surface, so that the beam does not refract at that surface. All the deviation caused by the prism takes ...

    2. How about an illustration to visually explain what it meant by the "prism dioptres" section? 3. Can prismatic lenses be included with bifocals, progressive lenses, polarizing, tinting, Crizol lenses, etc? 4. Hillary Rodham Clinton used prismatic lenses temporarily after her concussion, although her article doesn't mention that. What other ...

  11. Image geometry correction - Wikipedia

    en.wikipedia.org/wiki/Image_geometry_correction

    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 ...
