Abstract

La presente invenzione si riferisce ad un filtro non lineare pesato per segnale video; la caratteristica principale dell'invenzione consiste nel fatto che il filtro prevede una compensazione delle correlazioni spaziali e temporali attraverso un filtro non lineare, realizzato in modo da contrastare la legge di Weber.
