Classes

VMAF([enable_motion, clip_score, NEG, ...])

VMAF module Args: enable_motion (bool): if False set motion for all frames to 0 e.g. when computing on batch of images instead of video clip_score (bool): if True clip final VMAF score to [0,100] NEG (bool): if True compute VMAF NEG version, if False compute regular VMAF model_json_path (str): path to custom SVM model json, if None default model is used.
