Video recording true single-photon double-slit interference [PDF]
, 2016 As normally used, no commercially available camera has a low-enough dark noise to directly produce video recordings of double-slit interference at the photon-by-photon level, because readout noise significantly contaminates or overwhelms the signal.

Composite Video Noise Modelling and Suppressing
Signal and Image Processing, 2011 In order to tackle the recording video denoising problem with non-stationary image contents, a critical task is to estimate statistical properties of the composite noise in video signals. After investigation of a variety of test video sequences, based on the wavelet decomposition of the noise, the estimation can be conducted by empirical modeling of ...

Video Denoising and Enhancement via Dynamic Video Layering
, 2017 Video denoising refers to the problem of removing "noise" from a video sequence. Here the term "noise" is used in a broad sense to refer to any corruption or outlier or interference that is not the quantity of interest.
