Fogging, also known asblurring, is used forcensorship orprivacy. A visual area of a picture or movie is blurred to obscure it from sight. This form ofcensorship is used for sexually related images/scenes, hidinggenitals,pubic hair,buttocks, femalenipples/breasts, orsexual activity of any sort.Pixelization is a form of fogging. InJapan, where it is calledbokashi, fogging is employed on most films aired on public television that feature adult content of any kind.[1]
This form of editing also appears in television programs where an individual's face may not be shown due to legal or privacy concerns. As it does not contrast with the surrounding image very much, it is arguably preferable over most other forms of censorship.[citation needed] However, unlike other forms of visual censoring, it does not allow the preservation of any information about the original stimulus.[2] Fogging is also used if a scene is too bloody and gruesome to be rendered even in black and white, as well as on vehicle license plates (to protect the identity of a vehicle's owner), and over branded items and specific company names.
Although it is generally effective for obscuring details from the naked eye, fogging is not a sure method of removing information from images, as it is often possible to recover at least some information usingblind deconvolution techniques.
