'''Digital image processing''' is the use of a [[digital computer]] to process [[digital image]]s through an [[algorithm]].<ref>{{Cite journal |doi = 10.1109/MSP.2018.2832195|title = What is a Signal? &#91;Lecture Notes&#93;|journal = IEEE Signal Processing Magazine|volume = 35|issue = 5|pages = 175–177|year = 2018|last1 = Chakravorty|first1 = Pragnan| bibcode=2018ISPM...35e.175C |s2cid = 52164353}}</ref><ref name="Gonzalez 2018 p.

It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of [[Noise (signal processing)|noise]] and [[distortion]] during processing. Since images are defined over two dimensions (perhaps more), digital image processing may be modeled in the form of [[Multidimensional system|multidimensional systems]]. The generation and development of digital image processing are mainly affected by three factors: first, the development of computers;<ref>{{Cite journal |last1=Nagornov |first1=Nikolay N. |last2=Lyakhov |first2=Pavel A. |last3=Bergerman |first3=Maxim V. |last4=Kalita |first4=Diana I. |date=2024 |title=Modern Trends in Improving the Technical Characteristics of Devices and Systems for Digital Image Processing |journal=IEEE Access |volume=12 |pages=44659–44681 |doi=10.1109/ACCESS.2024.3381493 |issn=2169-3536|doi-access=free |bibcode=2024IEEEA..1244659N }}</ref> second, the development of mathematics (especially the creation and improvement of [[discrete mathematics|discrete mathematics theory]]);<ref>{{Cite journal |last1=Yamni |first1=Mohamed |last2=Daoui |first2=Achraf |last3=Abd El-Latif |first3=Ahmed A. |date=February 2024 |title=Efficient color image steganography based on new adapted chaotic dynamical system with discrete orthogonal moment transforms |url=https://linkinghub.elsevier.com/retrieve/pii/S0378475424000351 |journal=Mathematics and Computers in Simulation |volume=225 |pages=1170–1198 |language=en |doi=10.1016/j.matcom.2024.01.023|url-access=subscription }}</ref> and third, the demand for a wide range of applications in environment, agriculture, military, industry and medical science has increased.<ref>{{Cite journal |last=Hung |first=Che-Lun |date=2020-05-28 |title=Computational Algorithms on Medical Image Processing |url=https://www.eurekaselect.com/180828/article |journal=Current Medical Imaging |language=en |volume=16 |issue=5 |pages=467–468 |doi=10.2174/157340561605200410144743|pmid=32484080 |url-access=subscription }}</ref>
