Correspondingly, a range of digital image processing techniques possess direct physical analogs. For example, [[Fast Fourier transform|fast Fourier transform algorithms]] are commonly implemented in digital [[phase correlation]] and other digital image processing techniques. These digital [[Fourier transform|Fourier transforms]] can be considered to be the digitized approximation of methods utilizing [[Fourier optics#Fourier transforming property of lenses|Fourier transforming properties of an ideal lens]]<ref>{{Cite journal |last=Lugt |first=A.V. |date=1964-404 |s2cidtitle=250958169Signal detection by complex spatial filtering |url=http://dx.doi.org/10.1109/tit.1964.1053650 |journal=IEEE Transactions on Information Theory |volume=10 |issue=2 |pages=139–145 |doi=10.1109/tit.1964.1053650 |issn=0018-9448}}</ref>).
Basically any data can be represented in two types named as
1.Analog
2.Digital
if the pictorial representation of the data represented in analog wave formats that can be named as analog [[image]].
E.g.:
television broadcasting in older days.. through the dish antenna systems..
Where as the digital representation or storing the data in digital form is termed as a digital image processing
