Practical applications of face blurring and anonymization include:
Privacy and identity protection in public/private areas
Protecting children online (i.e., blur faces of minors in uploaded photos)
Photo journalism and news reporting (e.g., blur faces of people who did not sign a waiver form)
Dataset curation and distribution (e.g., anonymize individuals in dataset)…
and more!
