Abstract
Methods and systems for video processing include extracting flow features and appearance features from frames of a video stream. The flow features are processed using a flow model that is trained on a first set of training data. An output of the flow model is processed using a sub-network that is trained on the first set of training data and a second set of domain-specific training data to generate a flow parameter. The appearance features are processed using an appearance model that is trained on the first set of training data and that further processes the appearance features using the flow parameter, to classify the frames of the video stream. An action is performed responsive to the classified frames.
