receiving a frame of a video;
identifying, based on a blur level of the frame, whether the frame is a fully-blurred frame or a partially-blurred frame;
identifying, based on whether the frame is the fully-blurred frame or the partially-blurred frame, whether to obtain an analysis-based quality score using an analysis-based method or a model-based quality score using a model-based method;
obtaining, in response to the frame being the fully-blurred frame, the analysis-based quality score with respect to the fully-blurred frame;
obtaining, in response to the frame being the partially-blurred frame, the model-based quality score with respect to the partially-blurred frame; and
processing the video based on at least one of the analysis-based quality score or the model-based quality score to obtain a processed video,
wherein the analysis-based method and the model-based method are different.
