| 摘要 |
The present invention relates to a coding parameter independent method for reduction of blocking artefacts in a compressed image or video signal. For this purpose, the image is analysed in the vicinity of the block boundaries in order to measure the existence and strength of blocking artefacts and to detect image areas. Based on the analysis result map information for each pixel adjacent to a block boundary is generated. The filter mode for each block boundary is adaptively determined dependent on the map information and the image is filtered depending on the chosen filter mode.
