  • Abstract
    Median filtering is a simple digital technique for smoothing signals. A root signal is defined as an invariant signal to the median filtering. We describe directed graph representation for the root-signal set of median filters. The directed graph representation allows us to obtain a set of roots and the number of roots in a straightforward manner.
