Abstract: The method is for estimating original vector from severely distorted input vector utilizing synthetic discriminant function (SDF). The method comprises: (A) designing SDF filter corresponding to pattern groups; (B) obtaining the inner product of the SDF filter and distorted input vector with weight; (C) applying nonlinear function to the inner product vectors to separate the inner product values; (D) multiplying the vector by weight; (E) overlapping the patterns; and (E) taking signal function on the result of step (D) and returning to the step (B) until the original vector can be easily estimated.
