Video denoising

Video denoising is the process of removing noise from a video signal. Video denoising methods can be divided into:

  • Spatial video denoising methods, where image noise reduction is applied to each frame individually.
  • Temporal video denoising methods, where noise between frames is reduced. Motion compensation may be used to avoid ghosting artifacts when blending together pixels from several frames.
  • Spatial-temporal video denoising methods use a combination of spatial and temporal denoising. This is often referred to as 3D denoising.
