| Zusammenfassung: | The present invention disclosed methods for enhancing the subjective image quality of decoded images by applying a post-processing technique without amplifying coding artefacts and a corresponding apparatus. This is achieved by applying an image enhancement technique predominantly to image areas where coding artefacts are not likely to occur. These areas are identified based on the prediction error, which is employed to construct a mask for controlling the image enhancement process. |
