techniques to the domain of [[images]] — two-dimensional [[signal]]s such as [[photography|photographs]] or [[video]]. |

Most of the signal processing concepts that apply to one-dimensional signals — such as [[resolution]], [[dynamic range]], [[bandwidth]], [[filter (signal processing)| filtering]], etc. — extend naturally to images as well. However, image processing brings some new concepts — such as [[connected|connectivity]] and [[rotational invariance]] — that are meaningful or useful only for two-dimensional signals. Also, certain one-dimensional concepts — such as [[differential operators]], [[edge detection]], and [[domain modulation]] — become substantially more complicated when extended to two dimensions. |

A few decades ago, image processing was done largely in the [[analog]] domain, chiefly by [[optics|optical]] devices. Optical methods are inherently [[parallel]], and for that reason they are still essential to [[holography]] and a few other applications. However, as [[computers]] keep getting faster, analog techniques are being increasingly replaced by [[digital image processing]] techniques — which are more versatile, reliable, accurate, and easier to implement. |
