Abstract:
A method of suppressing noise in a signal, which comprises:measuring a noisy signal S(x,y,t) and carrying out a plurality of estimates for a corresponding noise-free useful signal S0(x,y,t) on a basis of the measurement of the noisy signal S(x,y,t); individually assigning each estimated value S0(1), S0(2), . . . , S0(k) obtained for each point (x,y,t) in carrying out the plurality of estimates a preference &agr;j(x,y,t), where j=1,2, . . . , k, and k is an integer; and forming a new estimated value {overscore (S)}0(x,y,t) for the useful signal from the estimated values S0(1), S0(2), . . . , S0(k) by arithmetic averaging weighted by the preference &agr;j(x,y,t).
