Abstract
Filtering is one of the most common applications of image processing. By filtering we mean the processing of the image in order to remove or reduce a particular unwanted component, for example noise, or to enhance or extract a particular set of features, such as edges. We can apply filters in both the spatial and frequency domains and many filters have equivalents in both domains. On the other hand, some filters operate exclusively in one domain or the other. Because the terminology used to describe both spatial and frequency domain filters often refers to spatial frequency features and effects we will first discuss the frequency domain filters.
