Abstract
The invention is directed to methods and circuit arrangements for video-rapid determination of the median of an evaluation window. In a first step, the gray values of one column of the evaluation window are transferred in accordance with their relative rank to window line memories; in a second step, selection circuit arrangements select gray values in parallel from all window line memories according to their rank relative to one another. Only these selected gray values are then processed in subsequent steps by processing circuit arrangements.
