MPEG coded digital video signal noise detection/noise reduction transcoding process having current image detected/coding search carried out finding reference coded macroblocks/noisy macroblock separated out. |
摘要 |
The detection method has a stream of digital words (IS) macroblock coded. A first step (21) reads the digital word stream to detect a current image of intra type, and a position of the macroblock. A search (22) is carried out for coding types and a table created with reference macroblocks having the coding. The macroblock assembly has a reference near position and a noisy macroblock (23) which is separated out from the other coding types.
