Apparatuses and methods for post-processing video images

摘要

An apparatus for post-processing a video image may include a filter configured to remove artifacts from pictures decoded by a video decoder; a differential picture encoder configured to produce compressed differential pictures based on the decoded pictures and the pictures filtered by the filter; and a differential picture decoder configured to reconstruct the filtered pictures based on the decoded pictures and the compressed differential pictures. A method for post-processing a video image may include filtering pictures decoded by a video decoder to remove artifacts from the decoded pictures; producing compressed differential pictures based on the decoded pictures and the filtered pictures; and reconstructing the filtered pictures based on the decoded pictures and the compressed differential pictures. A video image system may include a video decoder; a filter; a differential picture encoder; a memory; a differential picture decoder; and a display unit.
