The paper proposes a Bayesian algorithm for the reduction of additive video noise in the wavelet domain. Spatial and temporal redundancies that exist in a video sequence in the time domain also persist in the wavelet domain. This allows video motion to be captured in the wavelet domain. Based on this fact, a new statistical model is proposed for video sequences. We not only model the subband coefficients in individual frames, but also the wavelet coefficient difference occurring between two… CONTINUE READING
