Operations on Images

  • Jonas Gomes

Abstract

Image operations play an important role in computer graphics. Unless we explicitly say otherwise, in this chapter we will suppose that a digital image is given by its matrix representation. We’ll illustrate certain operations using one-dimensional signals instead of images; this allows a better understanding of the two-dimensional case. You can always think of a one-dimensional signal as the restriction of an image to a single scanline (row of its matrix representation).
