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
