DigitalImageProcessing Interestin digitalimageprocessin methods stemsfromtwoprincipal applicant- ion areas: improvement of pictorial information for human interpretation; and processin ofimagedataforstorage,transmission,andrepresentation forau-tenuous machineperception. An imagemaybe defined as atwo-dimensional function,f(x,y), where x andy arespatial(plane)coordinates,andtheamplitudeoffatanypairofcoordinates(x,y) is called the intensity or gray level of the image at that point. When x, y, and the amplitude values of f are all finite, discrete quantities, we call the image a digital image. The field of digital image processin refers to processin digital images by means of a digital computer. Note that a digital image is composed of a finite number of elements, each of which has a particular location and value. These elementsarereferred to aspicture elements,image elements,peels, andpixels. Pixel isthetermmostwidelyusedtodenotetheelementsofadigitalimage.
