1. the method for the noise of a coding that is used for reducing noisy image or image sequence may further comprise the steps:

  • -with predicated error (e q[x, y]) and predictive frame Or the addition of prediction piece, so that received code device (ENC) will further use or will be sent to the decoded frame (g of the output of decoder (DEC) in prediction loop q[x, y]) or decoding block, wherein, reference frame (g q[x, y]) or reference block (FR) partly consisted of by corresponding useful signal part and noise signal;

    And -utilize special-purpose noise to reduce filter (WF) to come only to described reference frame (g q[x, y]) or reference block (FR) carry out denoising, to reduce or to eliminate described reference frame (g q[x, y]) or the noise signal part of reference block (FR).
