Abstract:
A method may denoise a digital video signal produced by a photoelectric sensor as a matrix of pixel signals affected by both thermal noise and impulsive noise. The method may include estimating the noise level associated to the pixel signals, and filtering the pixel signals with an attenuation factor that is a function of the estimated noise level.
