  3. Video denoising - Wikipedia

    en.wikipedia.org/wiki/Video_denoising

    Generally, the luminance noise looks more like film grain, while chroma noise looks more unnatural or digital-like. [2] Video denoising methods are designed and tuned for specific types of noise. Typical video noise types are the following: Analog noise Radio channel artifacts High-frequency interference (dots, short horizontal color lines, etc.)

  4. Active noise control - Wikipedia

    en.wikipedia.org/wiki/Active_noise_control

    Sound is captured from the microphone(s) furthest from the mouth (the noise signal(s)) and from the one closest to the mouth (the desired signal). The signals are processed to cancel the noise from the desired signal, producing improved voice sound quality. In some cases, noise can be controlled by employing active vibration control. This ...
