In computer graphics, '''subsampling''' is the process of shrinking an image to a smaller size. Two commonly used methods are ''replacement'' and ''interpolation''. Replacement selects a single pixel from a group and uses it to represent the entire group. Interpolation uses a statistical sample (such as the mean) to create a new representation of the entire group.
