Anti-aliasing - In digital signal processing, spatial anti-aliasing is the technique of minimizing the distortion artifacts known as aliasing when representing a high-resolution image at a lower resolution.
Bézier surface - Bézier surfaces are a species of mathematical spline used in computer graphics, computer-aided design, and finite element modeling.
Bilinear interpolation - In mathematics, bilinear interpolation is an extension of linear interpolation for interpolating functions of two variables on a regular grid.
Cubic Hermite spline, the one-dimensional analogue of bicubic spline
Lanczos resampling - Lanczos resampling is a multivariate interpolation method used to compute new values for any digitally sampled data.
Natural neighbor interpolation - Natural neighbor interpolation is a method of spatial interpolation, developed by Robin Sibson.
Sinc filter - In signal processing, a sinc filter is an idealized filter that removes all frequency components above a given bandwidth, leaves the low frequencies alone, and has linear phase.
Spline interpolation - In the mathematical field of numerical analysis, spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a spline.
Tricubic interpolation - In the mathematical subfield numerical analysis, tricubic interpolation is a method for obtaining values at arbitrary points in 3D space of a function defined on a regular grid.
