[0063] The present invention determines the corresponding enhancement processing means by analyzing the video quality of the poor quality video image, and then analyzes the coding efficiency of the enhancement processing means, adopts the corresponding codec according to the coding efficiency, and considers the system while realizing the quality improvement. The processing efficiency.
[0064] Such as figure 1 As shown, the video image quality enhancement coding method of the present invention includes the following steps:
[0065] Steps to establish a video model to establish a video model for enhancement processing;
[0066] In the video scene segmentation step, a combination of video sequences belonging to the same scene in the video sequence is used as an enhancement processing group; the subsequent processing steps all use the enhancement processing group as the basic unit of processing.
[0067] The video quality analysis step is used to determine the video image quality of...
