[0055] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings.
[0056] image 3 It is a framework diagram of a video coding noise reduction process based on the H.264 / AVC (MPEG4-Part10) standard in an embodiment of the present invention. Such as image 3 As shown, in the embodiment of the present invention, a noise reduction processing link is added in the video encoding process, and the noise reduction processing link is set after the loop filtering link, and in specific implementation, it can also be set before the loop filtering link. In addition, for a video encoding process that does not include loop filtering, the noise reduction processing step only needs to be set after the image is reconstructed. The noise reduction processing link is used to perform full-pixel noise reduction processing on the reconstructed image of t...
