Apparatus for coding/decoding and filtering method for the reduction of artifacts in reconstructed images
Abstract
Adjacent blocks (44, 46) are identified in an image. Coding parameters for the adjacent blocks (44, 46) are identified (102). Deblock filtering (104) between the identified adjacent blocks (44, 46) is skipped if the coding parameters (55) for the identified adjacent blocks (44, 46) are similar and not skipped if the coding parameters (55) for the identified adjacent blocks (44, 46) are substantially different.
