Claim 1:
2. The video quality assessment method of claim 1, further comprising:
obtaining a spectral envelope with respect to each of a plurality of sub-areas included in the frame; and
estimating the blur level for each of the plurality of sub-areas based on the spectral envelope,
wherein the identifying whether the frame is the fully-blurred frame or the partially-blurred frame comprises:
identifying a number of the plurality of sub-areas in which the blur level estimated based on the spectral envelope exceeds a first threshold value;
identifying the frame as the fully-blurred frame based on the number exceeding a second threshold value; and
identifying the frame as the partially-blurred frame based on the number not exceeding the second threshold value.
