Bilinear interpolation

In mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation. It is usually applied to functions sampled on a 2D rectilinear grid, though it can be generalized to functions defined on the vertices of (a mesh of) arbitrary convex quadrilaterals. Bilinear interpolation is performed using linear interpolation first in one direction, and then again in the other direction. Although each step is linear in the sampled values and in the position, the interpolation as a whole is not linear but rather quadratic in the sample location. Bilinear interpolation is one of the basic resampling techniques in computer vision and image processing, where it is also called bilinear filtering or bilinear texture mapping. (Wikipedia).

Texture Sampling #2: Bilinear & Bicubic Samples

Following on from Part 1, I look at two common sampling methods that aim to reduce artefacts, bilinear and bicubic point sampling. The former linearly interpolates between neighbouring pixels, and the latter uses even further pixels to bias cubic splines to give a smoother contour between
