[0033] The video quality evaluation method includes: obtaining the subjective spatial domain distortion from the objective spatial domain distortion of the tested video sequence relative to the reference video sequence; obtaining the subjective temporal domain change from the subjective spatial domain distortion, according to the subjective Time domain changes to evaluate video quality. The specific implementation is as follows:
[0034] Suppose the set of all frames in the tested video sequence is N, and the set of all pixels in each frame of image is I. Any pixel in the nth frame in the tested video sequence is marked as S i, n (i∈I, n∈N), the pixel at the corresponding position in the previous frame (n-1) is S i, n-1 , Where the pixel at the corresponding position in the next frame (n+1) is S i, n+1 . S i, n The corresponding pixel in the reference video sequence is R i, n . Correspondingly, S i, n-1 And S i, n+1 Respectively correspond to R i, n-1 And R i, n+1 .
