REDUCTION OF BLOCKING ARTEFACTS IN IMAGE DECOMPRESSION SYSTEMS |
摘要 |
A method and apparatus for reducing blocking artefacts in a decompressed image signal includes inputting the decompressed video signal and detecting locations of block and image content edges therein. Image content and block edges are discriminated between to remove or conceal the image content edges and the remaining block edges transformed to produce an error correcting signal to smooth the block edges at the detected locations in a delayed version of the decompressed video signal. |
