We study the existence and uniqueness of solutions of a time-continuous version of the Neighborhood filter. In the line of previous works [12, 13, 14], we reformulate the usual pixel-based version of the filter introducing functional rearrangements, which are shown to be useful both for the filter analysis and for its fast implementation.
