Analog image processing

<p>Analog image processing is the use of an <a href="/facts/Optical_computing/aPl6UjC9">optical computer</a> to process physical, <a href="/facts/Image/hbjEdTXK">optical images</a> formed by light waves coming from an object, as opposed to the  <a href="/facts/Digital_image_processing/zenalNCf">digital image processing</a> and its use of <a href="/facts/Computer/SQe1aK05">digital computers</a> to process pixelated, <a href="/facts/Digital_image/3TNT47Mv">digital images</a>. Correspondingly, a range of digital image processing techniques possess direct physical analogs. For example, <a href="/facts/Fast_Fourier_transform/caT7UUCh">fast Fourier transform algorithms</a> are commonly implemented in digital <a href="/facts/Phase_correlation/hfCU0x3Q">phase correlation</a> and other digital image processing techniques. These digital <a href="/facts/Fourier_transform/XXhKJtc8">Fourier transforms</a> can be considered to be the digitized approximation of methods utilizing <a href="/facts/Fourier_optics/H4bVRGYx">Fourier transforming properties of an ideal lens</a>.
