Interpolation is a statistical technique which utilises related known variables to predict an unknown price or possible yield of an asset. Interpolation is often carried out by utilising known values that are placed in the same order as the unknown value.
In image processing, interpolation occurs when you resize or distort your image from one-pixel grid to another. At its core, interpolation is a straightforward mathematical idea. One may logically estimate the value of the set at uncalculated points if there is a generally consistent trend throughout a group of data points.
