Noise reduction for video signals

特許 係属中 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.
