Abstract
A collection of samples Si, representing, for example, an image is filtered in the following manner. A distinction is made between valid samples Si+ and non-valid samples Si− on the basis of auxiliary data AUX. Filtered samples So, which are associated with the valid samples Si+, are derived exclusively on the basis of the valid samples Si+. Accordingly, it is prevented that the filtered samples, which are associated with the valid samples, are mixtures of valid and non-valid samples. Such mixtures cause distortion, in particular if the valid and non-valid samples substantially differ in value.
