1. A method for encoding image data and noise parameters, said method comprising: a) receiving a video sequence comprising a first frame and a second frame, wherein said first frame comprises a first region and said second frame comprises a second region, which is static in relation to said first region; b) calculating a noise image region by determining a difference between said first region and said second region; c) measuring at least one noise parameter of said noise image region; d) detecting a smooth region of a frame of said video sequence; and e) denoising said smooth region using said at least one noise parameter as an a priori constraint in a total variation minimization process.
