1. An apparatus for filtering a sequence of pictures, comprising: a spatial filter for spatially filtering a picture in the sequence and at least one reference picture selected from among previous pictures and subsequent pictures in the sequence with respect to the picture; a motion compensator, in signal communication with said spatial filter, for forming, subsequent to spatial filtering, multiple temporal predictions for the picture from the at least one reference picture; a deblocking filter, in signal communication with said motion compensator, for deblock filtering the multiple temporal predictions; and a temporal filter, in signal communication with said deblocking filter, for temporally filtering the multiple temporal predictions and combining the multiple temporal predictions to generate a noise reduced version of the picture.
