Recursive median filters of increasing order: a variational approach
Stefano Alliney · IEEE Transactions on Signal Processing · 1996
For a certain class of signals, it is known that the recursive median filters provide a minimum of a related regularizing functional, defined by means of the l/sub 1/ norm. We generalize such results, and we show that a good approximation to the minima of such a functional can be obtained, for any signal, by means of successive applications of recursive median filters of increasing order.
