The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and comfortable binocular vision can be achieved. Other applications include yoked prism where the image is shifted an equal amount in each eye.
Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms , ambient lenses or performance glasses ) shift the visual field of both eyes to the same extent.
A pyramid is a polyhedron that may be formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form an isosceles triangle, called a lateral face. [3] The edges connected from the polygonal base's vertices to the apex are called lateral edges. [4] Historically, the definition of a pyramid has been described by ...
Double example: The scalenohedron with regular zigzag skew 2×2 -gon base vertices U, U', V, V' and right symmetric apices A, A' U = ( 3 , 0 , 2 ) , V = ( 0 , 3 , − 2 ) , A = ( 0 , 0 , 3 ) , U ′ = ( − 3 , 0 , 2 ) , V ′ = ( 0 , − 3 , − 2 ) , A ′ = ( 0 , 0 , − 3 ) , {\displaystyle {\begin{alignedat}{5}U&=(3,0,2),&\quad V&=(0,3,-2 ...
Lensfun is a free to use database and library for correcting lens distortion. OpenCV is an open-source BSD-licensed library for computer vision (multi-language, multi-OS). It features a module for camera calibration. DxO's PhotoLab software can correct complex distortion, and takes into account the focus distance.
Cavalieri's principle. This file represents the Cavalieri's Principle in action: if you have the same set of cross sections that only differ by a horizontal translation, you will get the same volume. In geometry, Cavalieri's principle, a modern implementation of the method of indivisibles, named after Bonaventura Cavalieri, is as follows: [1]
