<p>A method and a filter to eliminate the noise from a picture sequence, in which the received information X(x,y,t) is first filtered by a non-linear filter (9) and then with a recursive filter (10), the recursion (K(x,y,t)) of which is non-linearly adapted with a controller (11), and in which the filtered information Y(x,y,t) is stored in a memory (2). The previous filtered information Y(x,y,t-1) is obtained from the memory (2) for the recursive filtering of the next input information X(x,y,t). <IMAGE></p> |
