Abstract
Video methods and systems include extracting features of a first modality and a second modality from a labeled first training dataset in a first domain and an unlabeled second training dataset in a second domain. A video analysis model is trained using contrastive learning on the extracted features, including optimization of a loss function that includes a cross-domain regularization part and a cross-modality regularization part. The video methods and systems can support real-time decision making in various applications, such as security surveillance where immediate responses to detected actions are required.
