  • Bézier surface — Bézier surfaces are a species of mathematical spline used in computer graphics, computer aided design, and finite element modelling. As with the Bézier curve, a Bézier surface is defined by a set of control points. Similar to interpolation in… …   Wikipedia

  • Stairstep interpolation — In image processing, stairstep interpolation is a general method for interpolating the pixels after enlarging an image. The key idea is to interpolate multiple times in small increments using any interpolation algorithm that is better than… …   Wikipedia

  • Bilinear interpolation — In mathematics, bilinear interpolation is an extension of linear interpolation for interpolating functions of two variables on a regular grid. The key idea is to perform linear interpolation first in one direction, and then again in the other… …   Wikipedia

  • Image scaling — In computer graphics, image scaling is the process of resizing a digital image. Scaling is a non trivial process that involves a trade off between efficiency, smoothness and sharpness. As the size of an image is increased, so the pixels which… …   Wikipedia

  • Demosaicing — A demosaicing algorithm is a digital image process used to reconstruct a full color image from the incomplete color samples output from an image sensor overlaid with a color filter array (CFA). Also known as CFA interpolation or color… …   Wikipedia

  • Multivariate interpolation — In numerical analysis, multivariate interpolation or spatial interpolation is interpolation on functions of more than one variable. The function to be interpolated is known at given points and the interpolation problem consist of yielding values… …   Wikipedia

  • Interpolation — In the mathematical subfield of numerical analysis, interpolation is a method of constructing new data points within the range of a discrete set of known data points. In engineering and science one often has a number of data points, as obtained… …   Wikipedia
