Embodiment Construction
[0041] Below in conjunction with embodiment, further illustrate the present invention.
[0042]In order to quantitatively calculate the subjective quality of the HEVC decoded video, the present invention proposes a method for evaluating the subjective quality of the HEVC decoded video. The method first compares the frame rate of the decoded video and the original video, and calculates the average objective quality of the decoded video. Then according to the motion of the CTU in the image, take the larger top 25% motion vectors, calculate their average value, and then combine with the current encoding frame rate to represent the motion of the object in the video. Finally, the influence of image resolution on the subjective quality of decoded video is considered. Based on the above factors, the subjective quality evaluation model of HEVC decoding video is established.
[0043] The present invention proposes a new subjective quality evaluation method for HEVC decoded video by a...
