The shape of a 7-point 3D von Neumann style stencil. Iterative Stencil Loops (ISLs) or Stencil computations are a class of numerical data processing solution [ 1 ] which update array elements according to some fixed pattern, called a stencil. [ 2 ]
An illustration of the five-point stencil in one and two dimensions (top, and bottom, respectively). In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is a stencil made up of the point itself together with its four "neighbors".
Fixed-point computation refers to the process of computing an exact or approximate fixed point of a given function. [1] In its most common form, the given function satisfies the condition to the Brouwer fixed-point theorem: that is, is continuous and maps the unit d-cube to itself.
The Point Cloud Library (PCL) is an open-source library of algorithms for point cloud processing tasks and 3D geometry processing, such as occur in three-dimensional computer vision. The library contains algorithms for filtering, feature estimation, surface reconstruction, 3D registration, [5] model fitting, object recognition, and segmentation ...
A fast reconstruction algorithm for computed tomography imaging spectrometer (CTIS) is documented in the paper: Larz White, W. Bryan Bell, Ryan Haygood, "Accelerating computed tomographic imaging spectrometer reconstruction using a parallel algorithm exploiting spatial shift-invariance", Opt. Eng. 59(5), 055110 (2020).
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture . They may be stored in common image file formats , referenced by 3D model formats or material definitions , and assembled into resource bundles .
The point distribution model concept has been developed by Cootes, [1] Taylor et al. [2] and became a standard in computer vision for the statistical study of shape [3] and for segmentation of medical images [2] where shape priors really help interpretation of noisy and low-contrasted pixels/voxels.
Mechanism of how density of states influence V-A spectra of tunnel junction. Scanning tunneling spectroscopy is an experimental technique which uses a scanning tunneling microscope (STM) to probe the local density of electronic states (LDOS) and the band gap of surfaces and materials on surfaces at the atomic scale.
