====Image and sound processing==== {{main|Data processing}} [[Information]] can take the form of images, sound, video or other multimedia. [[Bit]]s of information can be streamed via [[signal]]s. Its [[Data processing|processing]] is the central notion of informatics, the European view on computing, which studies information processing algorithms independently of the type of information carrier β whether it is electrical, mechanical or biological. This field plays important role in [[information theory]], [[telecommunications]], [[information engineering]] and has applications in [[medical image computing]] and [[speech synthesis]], among others. ''What is the lower bound on the complexity of [[fast Fourier transform]] algorithms?'' is one of the [[List of unsolved problems in computer science|unsolved problems in theoretical computer science]]. {| style="border:1px solid #ccc; text-align:center; margin:auto;" cellspacing="15" |- | [[File:DIT-FFT-butterfly.png|96px]] | [[File:Bayer pattern on sensor.svg|96px]] | [[File:Opus quality comparison colorblind compatible.svg|96px]] | [[File:Quality comparison jpg vs saveforweb.jpg|96px]] | [[File:MeningiomaMRISegmentation.png|96px]] | [[File:Γtoms - Translation.svg|96px]] |- | [[Fast Fourier transform|FFT algorithms]] | [[Image processing]] | [[Speech recognition]] | [[Data compression]] | [[Medical image computing]] | [[Speech synthesis]] |}
