1. In recording process, the object light O and the reference light R interfere in the hologram plane and the interference fringe I is recorded on the hologram as shown in Eq. (1). In reconstruction process, the hologram is illuminated by the reconstruction light Re. If the reconstruction ...
Complete analytic representations are given for these 15 meromorphic functions in the complex plane deriving their asymptotic- and recursion relations. A general outline is presented on the way nested harmonic sums and multiple zeta values emerge in higher order calculations of zero- and single scale ...

A three-dimensional object will be projected onto a two-dimensional plane for display. If the z-axis is arranged to be normal to the plane of the display then no transformation of the x and y planes is required. However, depth information can be represented by allowing the z distance to ...
Despite their low cost, embedded computers often have lower tolerance for failure, since the results can vary from upsetting (when your new television crashes) to devastating (such as might occur when the computer in a plane or cargo ship crashes). In consumer-oriented embedded applications, ...
According to its principle, when four sinusoidal gratings with a phase difference of 90-degree in turn are projected onto the reference plane respectively, four fringe patterns captured from the reference plane can be expressed as Eqs (1–4): $${I}_{R1}(x,y)=R(x,y)\{a+b\,\cos [2...

Estimating the pose of a plane given a set of point correspondences is a core problem in computer vision with many applications including Augmented Reality (AR), camera calibration and 3D scene reconstruction and interpretation. Despite much progress over recent years there is still the need for a...
A fast and simple circuit for generating the MIP map LOD (level of detail) uses a look-up table (LUT) that stores values (1/2)log2 (X2 +Y2), wherein: (1) X and Y are in a single quadrant of the (X, Y) plane, for example, X≥0, Y≥0; (2) X≤Y or Y≤X; and (...
