Editing Annotation (section)

=== Digital imaging ===
In the [[digital imaging]] community the term annotation is commonly used for visible metadata superimposed on an [[digital image|image]] without changing the underlying master image, such as [[sticky note]]s, virtual laser pointers, circles, arrows, and black-outs (cf. [[redaction]]).<ref>{{Cite journal|last1=Pelka|first1=Obioma|last2=Nensa|first2=Felix|last3=Friedrich|first3=Christoph M.|date=2018-11-12|title=Annotation of enhanced radiographs for medical image retrieval with deep convolutional neural networks|journal=PLOS ONE|language=en|volume=13|issue=11|pages=e0206229|doi=10.1371/journal.pone.0206229|issn=1932-6203|pmc=6231616|pmid=30419028|bibcode=2018PLoSO..1306229P|doi-access=free}}</ref>

In the [[medical imaging]] community, an annotation is often referred to as a [[region of interest]] and is encoded in [[DICOM]] format.
