Linear processing of signals and images,Figure IX. 1 reminds us of the basic properties of a two-dimensional continuous linear filter, characterised by its impulse response R(.) or its transfer function G(.), both of which are Fourier transforms.

The image as an analogue signal,presented by a function .(.) of the two spatial variables . and . (fig.0.1). We shall call this a two-dimensional signal and write it as .(.). In introducing the concept of an image frequency spectrum (also known as a Fourier spectrum), we shall first consider the simpler case of a signal in one dimension, that is a function of a single variable.
