Abstract
A method for filtering digital video is disclosed. The method generally includes the steps of (A) checking a plurality of original blocks in an original field for a plurality of artifacts, wherein detection of the artifacts is based on an adjustable threshold, (B) first filtering each of the original blocks having at least one of the artifacts to remove the at least one artifact and (C) second filtering each of the original blocks lacking at least one of the artifacts to remove noise, wherein the second filtering is (i) motion compensated and (ii) adaptive to a respective noise level in each of the original blocks.
