Chapter 2
Polynomial Image Interpolation
2.1 Introduction
Image interpolation is a well known topic to most researchers who are interested in image processing. It pervades several applications. It is almost never a goal in itself, yet it affects both the desired results and the ways to obtain them. Interpolation may appear as a simple step in many image processing applications. Therefore, some authors give it less importance than it deserves. We try in this chapter to highlight the importance of image interpolation and cover the traditional work in this field.
Interpolation has been previously treated in the literature using different approaches [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25
