<p>A blocking effect de-noising method and apparatus are disclosed by the present invention. The method includes: dividing a current frame into macro blocks, wherein, a first macro block and a second macro block are adjacent macro blocks, and an area of the first macro block adjacent to the second macro block is a first edge area; judging whether the first edge area is a blocking effect area, if so, then marking the first edge area; calculating a percentage of the marked first edge area to the total edge area in the current frame; and performing blocking effect filtering if the percentage is greater than a preset first parameter. A blocking effect de-noising apparatus is also disclosed in the present invention, and the apparatus includes a division unit, a detection unit and a filtering unit. The method and apparatus of the present invention enables detecting image quality of the edge area between the adjacent macro blocks, and performing blocking effect filtering according to pixels between the adjacent two macro blocks if the image quality is lower than a preset level, thus effectively solving the problem in the prior art that the encoding performance of the macro-block-based variable encoding and quantization technique is low.</p> |
