Claim One:
1. A method for suppressing an undesired temporal pixel-value variation in a time sequence of video frames, the method including the steps of: computing, on the basis of values of a predetermined subset of pixels in each video frame in the time sequence, a set of number pairs of cumulative probabilities and corresponding quantiles, thereby yielding a sequence of sets of number pairs; determining, on the basis of the sequence of sets of number pairs, guidance number pairs of cumulative probabilities and corresponding quantiles; and replacing actual pixel values in the most recent frame in the time sequence by corrected pixel values in accordance with the set of guidance number pairs, wherein the guidance number pairs are determined in such manner that, responsive to said one or more image feature being resolved in a first other frame in the time sequence and unresolved in a second other frame of the time sequence, quantiles of two or more guidance number pairs substantially coincide with the purpose of not resolving one or more image features after the step of replacing actual pixel values.
