Example of bilinear interpolation on the unit square with the z values 0, 1, 1 and 0.5 as indicated. Interpolated values in between represented by color. In mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation.
Simple Fourier based interpolation based on padding of the frequency domain with zero components (a smooth-window-based approach would reduce the ringing).Beside the good conservation of details, notable is the ringing and the circular bleeding of content from the left border to right border (and way around).
Bilinear interpolation works by interpolating pixel color values, introducing a continuous transition into the output even where the original material has discrete transitions. Although this is desirable for continuous-tone images, this algorithm reduces contrast (sharp edges) in a way that may be undesirable for line art.
Each interpolation approach boils down to weighted averages of neighboring pixels. The goal is to find the optimal weights. Bilinear interpolation sets all the weights to be equal. Higher-order interpolation methods such as bicubic or sinc interpolation consider a larger number of neighbors than just the adjacent ones.
Bilinear sampling (also called "bilinear filtering"), a method in computer graphics for choosing the color of a texture; Bilinear form, a type of mathematical function from a vector space to the underlying field; Bilinear interpolation, an extension of linear interpolation for interpolating functions of two variables on a rectilinear 2D grid
Another simple method is bilinear interpolation, whereby the red value of a non-red pixel is computed as the average of the two or four adjacent red pixels, and similarly for blue and green. More complex methods that interpolate independently within each color plane include bicubic interpolation, spline interpolation, and Lanczos resampling.

Multivariate interpolation is the interpolation of functions of more than one variable. Methods include nearest-neighbor interpolation, bilinear interpolation and bicubic interpolation in two dimensions, and trilinear interpolation in three dimensions. They can be applied to gridded or scattered data.
