Abstract

Filters and operators used for smoothing signals are fundamental parts of the preprocessing stage. In Sect. 12.9 we already showed how the Fourier transform can be used to filter a signal. Filters, in general, can be designed for two different domains: the frequency and the spatial-domain. In the following sections we will filter images in the spatial domain, rather than using the spectral domain.
